How many grams of oxygen gas can be produced from the explosion of 454.2 grams of nitroglycerin?
The total pressure of a mixture of gasses is the sum of the individual pressures.
Volume is inversely proportional to pressure as temperature is held constant.
At constant volume, the pressure exerted by a given mass of gas varies directly with the absolute temperature.
Volume is proportional to the absolute temperature of a gass as pressure is held constant.
