Dry ice (solid CO2) has occasionally been used as an "explosive" in mining. A hole is drilled, dry ice and a small amount of gunpowder are placed in the hole, a fuse added and the hole plugged. When lit the exploding gunpowder rapidly vaporizes the dry ice and immense pressure is built up. If 0.75kg of dry ice is placed in a cavity with a volume of 950mL and the ignited gunpowder heats the CO2 to 447 degrees Celsius, what is the final pressure inside the hole?

R=0.0821 L.atm/mol.K
