1
Concentration in Solution

2
Mass Percentage Mass % of A = mass of A in solution total mass of solution 100

3
Parts per Million and Parts per Billion ppm = mass of A in solution total mass of solution 10 6 Parts per Million (ppm) Parts per Billion (ppb) ppb = mass of A in solution total mass of solution 10 9

4
moles of A total moles in solution X A = Mole Fraction (X) In some applications, one needs the mole fraction of solvent, not solute make sure you find the quantity you need!

5
mol of solute L of solution M = Molarity (M) We have discussed this a few times, very quickly this year. Since volume is temperature-dependent, molarity can change with temperature.

6
mol of solute kg of solvent m = Molality (m) Since both moles and mass do not change with temperature, molality (unlike molarity) is not temperature-dependent.

7
Dilution When diluting a stock solution use the formula: M 1 V 1 = M 2 V 2 M 1 - original molarity V 1 - volume of the original solution M 2 – new molarity V 2 – new volume (in whatever unit you started with)
