Three gases were added to the same 4.4L container. The total pressure of the gases was 772 torr at room temperature (25.0 celsius). If the mixture of the compound contained 0.27g Oxygen gas, 0.55g of carbon dioxide, and an unknown amount of nitrogen gas.
(a) What is the total number of moles of gas in the container?
(b) What is the number of grams of nitrogen in the container?
