1) At 29C and 756 torr, a gas occupies 2.50L. If the temperature is increased to 159C and the pressure is increased to 1550 torr, what volume does the gas occupy?

2) A 15L flexible container has 0.5 moles N2 gas at a pressure of 0.85 atm, a temperature of -30.0C, if 10g of N2 is added to the container, the pressure increased to 1.0 atm and the temperature increased to 0.0C, what is the new volume of the container?
