Answer
a) $504 L$
b) $80.64 L$
c) $49.28 L$
d) $604.8 L$
Work Step by Step
At Standard Temperature and Pressure (STP) which is $0^{\circ}C$ and 1 atm of pressure, the volume occupied by any gas is 22.4 L. So to find how many liters a gas occupies we can simply multiply the moles of the gas by 22.4 L.
a) $22.5 mols Cl_{2}\times22.4 = 504 L$
b) $3.6 mols N_{2}\times22.4 = 80.64 L$
c) $2.2 mols He\times22.4 = 49.28 L$
d) $27 mols CH_{4}\times22.4 = 604.8 L$
