1. A 1.0 L sample of a gaseous compound of hydrogen, carbon, and nitrogen gave upon combustion 2.0 L of CO2, 3.5 L of H2O vapor, and 0.50 L of N2 (with all gas volumes measured at the same T and P). What is the empirical formula of the compound?

2. A 6.01 g sample of a gaseous carbon-hydrogen compound is found to contain 4.80 g C and 1.21 g H. At STP, 762 mL of the gas has a mass of 1.02 g. What is the molecular formula of the compound?

3. An adult takes about 15 breathes per minute with each breath having a volume of 500 mL. If the air that is inhaled is dry, but exhaled at 1 atm is saturated with water vapor at 37°C, what is the mass of water lost from the body in one hour. The vapor pressure of water at 37°C is 47.1 torr.
