Volume interconverting molarity

Interconversion. A. simple way of interconverting amounts and volumes of any.partlcular solution is to divide the amount and volume by. a factor of 10 thus a molar solution of a substance contains 1 molL which is equivalent to IrrimolmL , or 1/zmol small volume of solution of known coricentration, e.g. to calculat the amount of NaCI present in 50/iL of a solution with a concentration (molarity) of 0.5molL NaCI ... 

Interconvert mass, number of moles, number of molecules, and (using density) the molar volume of a substance (Section 2.f, Problems f-12). 

Since both volume for volume and weight for volume units are in common use for regulations and quoting air pollution results, it is necessary to be able to interconvert between these units. To obtain a value in mg/m from a value in ppm one has to multiply the ppm value by the molecular weight of the component of interest in grams, and divide by 24.46, the molar volume at 25°C (Eq. 2.7). 

The concentration of a solution can be expressed in different terms (molarity, molality, parts by mass, parts by volume, and mole fraction). Because a concentration is a ratio involving mass, volume, and/or amount (mol), the various terms are interconvertible. 

Express concentration in terms of molarity, molality, mole fraction, and parts by mass or by volume and be able to interconvert these terms ( 13.4) (SPs 13.3-13.5) (EPs 13.37-13.58)... 

SECTION 4.5 The concentration of a solution expresses the amount of a solute dissolved in the solution. One of the common ways to express the concentration of a solute is in terms of molarity. The molarity of a solution is the number of moles of solute per liter of solution. Molarity makes it possible to interconvert solution volume and number of moles of solute. Solutions of known molarity can be formed either by weighing out the solute and diluting it to a known volume or by the diution of a more concentrated solution of known concentration (a stock solution). Adding solvent to the solution (the process of dilution) decreases the concentration of the solute without changing the number of moles of solute in the solution... 

In order to interconvert molality and molarity, we need to know the density of the solution. Figure 13.19 T outlines the calculation of the molarity and molality of a solution from the mass of solute and the mass of solvent. The mass of the solution is the sum of masses of the solvent and solute. The volume of the solution can be calculated from its mass and density. 

The concentration of a solution is expressed through different concentration terms, including molarity, molality, mass percent, volume percent, and mole fraction. These terms are interconvertible. Section 13.4)...
