1. If an ideal gas initially at 1.00 bar and 1.30 L is compressed at constant temperature to a volume of 0.600 L, what is the final pressure of the compressed gas?

2. A mixture of ideal gasses having a total mass of 27.0g is placed in a 9.00 L vessel at 293 K. The equilibrium pressure is measured to be 1.20 bad. Calculate the average molar mass of the gas mixture.

3. What is the mass of xenon gas contained in a. 1.20 L vessel at 3.70 bar and 343 K?

4. The international union of pure and applied chemistry has adopted 273.15 K and 1 bar as a standard temperature and pressure (STP) for gasses. Under these conditions, the molar volume of ideal gas is 22.71 L. What is the molar volume or ideal gas at 354 K and 0.900 bar?
