Test on Friday:

gram molecular mass

% composition

Hydrates

% hydration

Mole

Molar volume for gases (1 mole = 22.4 L)

Formulas for conversion to moles:

mol = mass/gmm mol = liters/22.4 L gas @ STP mol = molecules/6.02 x 10^23

Empirical formulas

Determining empirical formulas from % composition

Determining molecular formula from empirical formula

- using coefficient ratios
- mole-mole problems
- volume-volume problems
- mole-liter problems
