5.17 Calculate the volume occupied by 8.8 g of CO2 at 31.1°C and 1 bar pressure.
R = 0.083 bar L K
–1 mol–1.

  pV = mMRt  pV = mMRt
  V = mRTMp  V = mRTMp
Here, m = 8.8 g Here, m = 8.8 g 
R = 0.083 bar LK-1 mol-1R = 0.083 bar LK1 mol1
T = 31.1°C = 304.1 K T = 31.1°C = 304.1 K 
M = 44 g p = 1 bar M = 44 g p = 1 bar 

   Thus, volume (V) = 8.8×0.083×304.144×1   Thus, volume (V) = 8.8×0.083×304.144×1
                                   = 5.04806 L                                   = 5.04806 L
                                    = 5.05 L                                    = 5.05 L
Hence, the pay load of the balloon is 3811.1 kg.
