5.2/3 Pre-Quiz Key
For objective 5.2, you must be able to use the combined gas law, the ideal gas law (units are very important in this law), and Dalton's law of partial pressures. For Dalton's law of partial pressures, make sure you know how to use mole ratios to find partial pressures as well.

For objective 5.3, you need to able to use stoichiometry with the ideal gas law.

Our lab on Friday is important for the Dalton's Law of Partial Pressures question on the quiz. The total pressure when a gas is collected over water is equal to the pressure of water vapor PLUS the pressure of the gas.

Quiz is Friday.
