General Chemistry 1: Ideal Gas Law

A sample of nitrogen has a volume of 883 mL and a pressure of 741 torr. What pressure will change the volume to 655 mL at the same temperature?

What will be the final pressure of a sample of nitrogen with a volume of 955 mL at 745 torr and 25 $^{\circ}$C if it is heated to 62 $^{\circ}$C and given a final volume of 1155 mL?

How many grams of Ar are in a 12.0 L cylinder of argon at a pressure of 57.8 atm and a temperature of $25^{\circ}$C ?

Rank the following gasses in order of increasing rates of effusion:

O$_2$

Ar

CO$_2$

N$_2$
