chpt. 3.3 -- empirical formulas

This is intro. to Chemistry class notes on empirical formulas. This document goes into detail about empirical formulas, calculating an empirical formulas from the percent composition, finishing calculations by turning moles into a mole ratio, what to do if the normalized ratios aren't whole numbers, how you can gat the molecular formula from the empirical formula, steps to determine molecular formulas from the percent composition, balanced equations giving ratios of quantitative information, mole ratios being definitions that MUST come from a balanced equations, quantities in a chemical equation, chemical equations that don't give gram ratios (only mole ratios), the summary of stoichiometry and it's impact on manipulating info in a balance equations, and identifying and calculating the limiting reactants in a chemical equation.
