1. Use the Van der Waals equation to calculate the pressure exerted by 1.00 mol of Cl2; in 22.41 L at 0.0 degrees C. The constants for Cl are a = 6.49 L2 atm/mol2 and b = 0.0526 L/mol.
2. How much potassium chlorate is needed to produce 20.0 mL of oxygen at 670 mm Hg and 20 degrees C.
3. A certain compound containing only carbon and hydrogen was found to have a vapor density of 2.550 g/L at 100 degrees C and 760 mm Hg. If the empirical formula of this compound is CH, what is the molecular formula of this compound?
