I need help with 4 chemistry questions so please answer it for me

1. 0.475 mol of a gas occupies 25.0 L at room temperature and pressure. What is its molar volume at these conditions?

2. What is the value of R, the gas constant, when it has units of L-kPa/mol-K?

3. What volume in mL will 13.2 g of CO2 occupy at 292 K and 1.55 atm of pressure? 4. A 50 mL Erlenmeyer flask was determined to have a volume of 61.9 mL. A sample of nitrogen gas is put into the flask. What is the volume of the nitrogen gas in L?

5. A sample of oxygen gas occupies a volume of 0.200 L at 60.0C and 500. mmHg of pressure. What will its volume be in L at STP?
