Answer
a) $474.88 L$
b) $4.816 L$
c) $8.1536 L$
d) $192.64 L$
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) $21.2 mols N_{2}O\times22.4 = 474.88 L$
b) $0.215 mols CO\times22.4 = 4.816 L$
c) $0.364 mols CO_{2}\times22.4 = 8.1536 L$
d) $8.6 mols C_{2}H_{6}\times22.4 = 192.64 L$
