Section 1: Pressure conversions

A sealed tank contains the following mixture of gases: 2.0 grams of helium, 48.0 grams of oxygen, 14.0 grams of nitrogen, 64.0 grams of sulfur dioxide, and 9.0 grams of hydrogen gas. If the total pressure is 800.0 kPa, then find the partial pressure of each gas. Nitrogen is collected over water at 21.5(C (vapor pressure is 18.7 mm Hg). ................
