Conversion factors volume

The component factor gives the unit yield for each component and includes a volume conversion factor. The factors can be obtained from tables. 

It is always advisable, incidentally, to measure the density of a saturated solution at the same time that the equilibrium saturation concentration is being measured, for the simple practical reason that density is the mass-volume conversion factor, and this quantity is frequently required in process calculations. Sohnel and Novotny (1985) have published an extensive compilation of concentration-density data for aqueous solutions of inorganic salts. 

The problem now becomes, What volume of SO2 is produced by the reaction of 2.48 L O2, with both gases at the same temperature and pressure This makes the volume-conversion factor the same as the mole ratio from the equation. Plan and complete the problem. 

U.S. regulations define this standard as foUows proof spirit shaU be held to be that alcohoHc Hquor which contains one-half its volume of alcohol of a specific gravity of 0.7939 at 15.6°C ie, the figure for proof is always twice the percent alcohol content by volume. For example, 100° proof means 50% alcohol by volume. In the United Kingdom as weU as Canada, proof spirit is such that at 10.6°C alcohol weighs exactiy twelve-thirteenths of the weight of an equal bulk of distiUed water. A proof of 87.7° indicates an alcohol concentration of 50%. A conversion factor of 1.142 can be used to change British proof to U.S. proof. 

Conversion Factors between Volume and Mass Units of Concentration (25°C, 760 mm Hg)... 

It is often necessary to convert a measurement expressed in one unit (e.g., cubic centimeters) to another unit (liters). To do this we follow what is known as a conversion factor approach. For example, to convert a volume of 536 cm3 to liters, the relation... 

The quotient 1 L/1000 cm3, which is called a conversion factor, is multiplied by 536 cm3. Because the conversion factor equals 1, this does not change the actual volume. However, it does accomplish the desired conversion of units. The cm3 in the numerator and denominator cancel to give the desired unit liters. 

The relation 1 L = 1000 cm3 can be used equally well to convert a volume in liters, say, 1.28 L, to cubic centimeters. In this case, the necessary conversion factor is obtained by dividing both sides of the equation by 1 L ... 

In a practical sense, density can be treated as a conversion factor to relate mass and volume. Knowing that mercury has a density of 13.6 g/mL, we can calculate the mass of 2.6 mL of mercury ... 

Strategy (1) Start by calculating the number of moles of Fe2+. Then (2) use the coefficients of the balanced equation to find the number of moles of Mn04. Finally, (3), use molarity as a conversion factor to find the volume of KMn04 solution. 

As pointed out in Chapter 3, a balanced equation can be used to relate moles or grams of substances taking part in a reaction. Where gases are involved, these relations can be ex tended to include volumes. To do this, we use the ideal gas law and the conversion factor approach described in Chapter 3. 

Specific volume is a conversion of specific gravity into cubic inches per pound. Since the volume of material in a product is the first bit of information established after its shape is formulated, the specific volume is a convenient conversion factor for weight ... 

Due to a fortuitous cancellation of units, volume can be expressed in cm3 and pressure in MPa to give the same results as volume in m3 with pressure in Pa, without invoking any conversion factors. Thus pV in Pa m3 gives Joules as does pV in MPa cm3. 

Therefore, if we work in pascals and cubic meters, the work is obtained in joules. However, we might have expressed the pressure in atmospheres and the volume in liters. In this case, we may need to convert the answer (in liter-atmospheres) into joules. The conversion factor is obtained by noting that 1 L = 10 3 m3 and 1 atm = 101 325 Pa exactly therefore... 

Quantitation is performed by the calibration technique. Construct a new calibration curve with methomyl oxime standard solutions (0.2, 0.4, 0.6, 0.8 and 1.0 xgmL in acetone) for each set of analyses. Plot the peak area against the injected amount of methomyl oxime on logarithmic paper. As the amount of alanycarb is measured in terms of its oxime derivative, a conversion factor of 3.8 (the molecular weight ratio of alanycarb to methomyl oxime) should be applied to obtain the net amount. The injection volume should be kept constant as the peak area varies with the injection volume in flame photometric detection. Before each set of measurements, check the GC system by injecting more than one standard solution containing ca 2-10 ng of methomyl oxime. 

Subsequently, individual data on exposure are converted to dose by using conversion factors (OECD/NEA, 1983). The choice of the appropriate numerical value depends on physiological parameters (e.g. respiratory minute volume) as well as physical characteristics of the inhaled aerosol (e.g. particle size). Mean values range typically from about 5 mSv/WLM (non-occupational exposure) to about 10 mSv/WLM (occupational exposure). 

We begin with the amount of reparations and obtain the volume in cubic kilometers with a series of conversion factors. 

A We must convert mass H2 —> amount of H2 -> amount of A1 —> mass of A1 -> mass of alloy -> volume of alloy. The calculation is performed as follows each arrow in the preceding sentence requires a conversion factor.
