Molarity Vocab & Basic Gas Laws

Molarity =

• mass of solute / moles of solvent

• moles of solute / volume of solvent

We used a 0.1M NaOH solution in our titration. That means 0.1 mol NaOH is dissolved in 1L of water. What is the solvent in this solution?

• coffee

• water

• NaOH

• alcohol

A balloon is filled with 35.0 L of helium in the morning when the temperature is 20.00 C. By noon the temperature has risen to 45.00 C. Which gas law would I use to find the balloon's new volume?

• Boyle's Law

• Charles' Law

• Gay-Lussac's Law

• The Combined Gas Law

Boyle's Law relates (a)   and volume. (spelling matters)

In Gay-Lussac's Law, (a)   is constant. (spelling matters)
