Calculating Molar Mass and Moles:
Molar Mass (g/mol) = Mass of Element (g) x Number of Atoms
Moles (mol) = Mass Given (g) / Molar Mass (g/mol)
Atoms of Molecules/Compounds=Moles x Avogadro's Number
Mass of Element
Number of Atoms
1) Name each of the following changes of state:
a) liquid to gas = Vaporation.
b) solid to gas = Sublimation.
c) gas to liquid = Condensation.
d) solid to liquid = Fusion (Melting)
2) Describe what happens to the molecules in a substance when it melts.

Solubility Rules Worksheet
Directions: Use the SOLUBILITY RULES section of your Chemistry Reference Tables (p.6) to help you answer
1. Circle the following compounds that are soluble in water.
Molarity and pH
Molar Mass = Atomic Mass of Elements x No. of Atoms
Moles = Mass Given / Molar Mass
Molarity = Moles / Volume (L)
pH = LOG (Molarity Concentration)
pOH = 14 - pH
What is the pH of the H3PO4 if 35g are dissolved in 0.75 L of wate
