Question:
1. Laboratory gas cylinders are typically filled to 200 bar. What is the molar volume for oxygen under these conditions if it follows VdW (L/mol at 25A?°C)? a=1.364L^2atm/mol^2 and b=0.0319L/mol
2. A chemical reaction occurs in a container with a cross-sectional area of 50.0 cm^2. As a result of the rxn, a piston is pushed out 15-cm against an external pressure of 147kPa. Determine the work done by the system (J).
