Question

A gas occupies 15 liters at a pressure of 80.0 mm Hg. What is the volume when the pressure is increased to 100.0 mm Hg?

Answer 1

We use Boyle's law: `P_1V_1=P_2V_2`; temperature and moles are constant.

Explanation:

`V_2 =(P_1V_1)/P_2` `=` `80*mm*Hg` `xx` `15*L` `xx` `1/(100*mm*Hg)`

So the answer is `4/5` `xx` `15*L` `=` `12*L`.
