A steel container contains 300g of ideal gas at a pressure of 1.35 x 10^{6}Pa and temperature of 77^{o}C. When the tank is checked later, the temperature is dropped to 22^{o}C and the pressure has fallen to 8.7 x 10^{5}Pa. How many grams of gas leaked out of the tank?

2. Relevant equations

PV = NkT

3. The attempt at a solution

first, converting: 77^{o}C = 350.15K and 22^{o}C = 295.15K

The problem is, i do not know how to link mass to the equation of PV = NkT
