2 methods for finding volume of a solid Pycnometer’s purpose D = mass/volume Definition Empirical formula Adding excess of one reactant Know what it represents How the lab we did allowed us to calculate it Reaction between Mg + HCl What the #’s represent in a chemical formula Calculate % yield Purpose of recrystallization How to vacuum filter something properly Balanced equations Write chemical formula of product given 2 ions Titration Phenolphthalein – purpose, how it works Dilution - M1V1 = M2V2 Titration Purpose of starch Find moles of product given moles of reactant Definition Calculate from formula Scientific law shown in this lab What ∆H (+) or (-) means Difference between a strong and weak acid PV=nRT, use formula Know what each letter stands for and correct units PV=nRT Find Molecular Mass given other values

Fractional uncertainties, Significant figures MATH – find moles of solids or solutions, or mass of solids given other values (Molarity, Molar Mass, Mass)
