Formulas and constants for the test that you can put on a card!

Chap 7 Nomenclature

1 mol of X = Formula mass = gram atomic mass from the periodic table

% composition = mass of the element / molar mass of formula x 100

Chap 8 Balancing equations

Chemical equations

no formulas

Chap 9 Stoichiometry

% yield = actual yield (experiment) / Theoretical yield(stoichiometry) x100

Chap 10 Phase changes as temp increase = faster molecular motion Graham’s law

Chap 12 Solutions

% mass = Mass of solute/mass solution x 100

Molarity = moles of solute/ L of soln.
