Hello Student
pV = nRT, we can replace n by m/M, where,
m = mass of gas
M = Molecular mass in gmol–1
So, pV = (m/M) X RT,
Hence, V = (mRT)/ Mp
Quantites given are :
m = 8.8 g
R = 0.083 bar LK–1 mol–1
T = 31.1°C = 304.1 K
M = 44 g
p = 1 bar
Plugging these values in above equation we get, V = 5.05 L.
