Kilogram , 26 table

The basic unit of mass in the SI system is the kilogram (Table 1-6). The kilogram is defined as the mass of a platinum-iridium cylinder stored in a vault in Sevres, near Paris, France. A 1-lb object has a mass of 0.4536 kg. The basic mass unit in the earlier metric system was the gram. A U.S. five-cent coin (a nickel ) has a mass of about 5 g. 

Three studies present the minimum lethal dose and all three are in general agreement that somewhere in excess of 2000 pg represents a potentially lethal dose. There is more variation in the estimated minimum lethal dose per kilogram (Table 4.2). The highest reported shellfish toxin levels are approximately 20,000 pg/100 g tissue [15,20]. At this level, a lethal dose may be ingested from as little as two 4 g mussels. If it is assumed that a lethal dose per kilogram is 36 pg, then a child may consume a lethal dose from eating a fraction of a mussel. 

Using the data in the table scientists, students, and others that are familiar with the periodic table can extract infomiation conceming individual elements. For instance, a scientist can use carbon s atomic mass mass to detemiine how many carbon atoms there are in a 1 kilogram block of carbon. 

Physical Properties. Table 1 (2) shows that olefin fibers differ from other synthetic fibers in two important respects (/) olefin fibers have very low moisture absorption and thus excellent stain resistance and almost equal wet and dry properties, and (2) the low density of olefin fibers allows a much lighter weight product at a specified size or coverage. Thus one kilogram of polypropylene fiber can produce a fabric, carpet, etc, with much more fiber per unit area than a kilogram of most other fibers. 

Total world production of manganese ores in 1992 was about 6.7 x 10 metric tons manganese content, down from 9.3 x 10 in 1989. Table 13 shows the price of a kilogram of manganese in terms of constant U.S. 1987 doUars, ie, adjusted for inflation. 

Nuts are rich in protein and fat most commercially important nuts supply about 28 MJ /kg (6600 kcal/kg) of kernel, more than most other foods (Table 2) cereals supply about 15 MJ /kg (3640 kcal/kg) meats about 7.5 MJ /kg (1790 kcal/kg) and fresh fmits less than 2.8 MJ /kg (660 cal/kg). The energy content in kilojoules (1 food calorie or cal = 4.184 kJ) per kilogram of food is calculated by the following formula ... 

The viscosity ratio or relative viscosity, Tj p is the ratio of the viscosity of the polymer solution to the viscosity of the pure solvent. In capillary viscometer measurements, the relative viscosity (dimensionless) is the ratio of the flow time for the solution t to the flow time for the solvent /q (Table 2). The specific (sp) viscosity (dimensionless) is also defined in Table 2, as is the viscosity number or reduced (red) viscosity, which has the units of cubic meters per kilogram (m /kg) or deciUters per gram (dL/g). The logarithmic viscosity number or inherent (inh) viscosity likewise has the units m /kg or dL/g. For Tj g and Tj p, the concentration of polymer, is expressed in convenient units, traditionally g/100 cm but kg/m in SI units. The viscosity number and logarithmic viscosity number vary with concentration, but each can be extrapolated (Fig. 9) to zero concentration to give the limiting viscosity number (intrinsic viscosity) (Table 2).

Let us consider the overhead-cost data for Table 9-39 with 10 million kg per month as the standard production rate. The static budgeted overhead is then 150,000 per month, or 1.5 cents per kilogram. We assume that the actual overhead is 186,000 for a month in which 12 milhon kg was produced. Then, the static budgeted overhead cost would be 12 million(I.5), or 180,000 per month. Therefore, the variance is 186,000 — 180,000 = -t- 6000, which is unfavorable because 6000 more was spent than was anticipated. 

The IUPAC definition of pH39 is based upon a 0.05M solution of potassium hydrogenphthalate as the reference value pH standard (RVS). In addition, six further primary standard solutions are also defined which between them cover a range of pH values lying between 3.5 and 10.3 at room temperature, and these are further supplemented by a number of operational standard solutions which extend the pH range covered to 1.5-12.6 at room temperature. The composition of the RVS solution, of three of the primary standard solutions and of two of the operational standard solutions is detailed below, and their pH values at various temperatures are given in Table 15.4. It should be noted that the concentrations are expressed on a molal basis, i.e. moles of solute per kilogram of solution. 

This thermodynamically based methodology provides predictions of the lithium capacities in addition to the electrode potentials of the various three-phase equilibria under conditions of complete equilibrium. This information is included as the last column in Table 2, in terms of the number of moles of lithium per kilogram total alloy weight. 

We found that the optimal reaction protocol was to add a solution of a-bromo ketone in THF to the amidine in aqueous THF in the presence of potassium bicarbonate under vigorous reflux. Using this procedure, 2,4-disubstituted imidazoles were isolated in excellent yields with >95% purity without column chromatography. Aromatic and aliphatic a-halo ketones participate in this reaction with a variety of aromatic amidines, as indicated in Table 1. Particularly noteworthy is that reactions involving pyridylamidines or chloroacetone are substantially more robust using this process (entries 3 and 4). We have successfully used this protocol on a multi-kilogram scale.

Measuring and Using Numbers Calculate the average value of the e/m ratio from the results in Data Table 3. Note that the units of the e/m ratio are Coulombs per kilogram (C/kg). 

The ICRU (1980), ICRP (1984), and NCRP (1985) now recommend that the rad, roentgen, curie, and rem be replaced by the SI units gray (Gy), Coulomb per kilogram (C/kg), Becquerel (Bq), and sievert (Sv), respectively. The relationship between the customary units and the international system of units (SI) for radiological quantities is shown in Table D-5. 

An annual estimated cost of approximately 938,835,000 is required for labor and equipment to apply 204.5 million kilograms of herbicides to 147.6 million hectares of cropland in the United States (Table IV). Mechanical tillage to control weeds between cropping seasons and interrow tillage of crops has been used for centuries as a very effective method of weed control. Approximately 50% of all tillage between crops is done to control weeds. The number of cultivations required for effective weed control within a row crop varies from two to five during a cropping season.
