a tank in a room at 19 C is initially open to the atmosphere on a day when the barometric pressure is 102kpa. A block of dry ice (solid CO2) with a mass of 15.7 kg is dropped into the tank which is then sealed .The reading on the tank pressure initially rises very quickly then much more slowly eventually reaching a value of 3.27 mpa. A ssume T final=19C. How many moles of air in the tank initially ?
