we should use RK EOS

A company in the United States transported 23000kg of propylene by a road tanker. The propylene was loaded in the plant at 1=C. The temperature of weather broadcasting in that day was 8C. The road tanker transporting propylene exploded on the way. The volume of the tank was 44.4m. Use RK EOS for your calculations. Road tanker a) Calculate the pressure at which the tanker was exploded. b) If we use the same road tanker in Saudi Arabia during summer to transport propylene, what is maximum mass that you suggest to be loaded to the tanker without having any catastrophic failure in transporting propylene
