Calculate the number of grams of nitrogen gas, N2, in a container that has a volume of 7.50 L at a pressure of 1200 mm Hg and a temperature of 38.2 degrees Celsius. (R=0.0821 L*atm/mole*K)
1 answer
PV = nRT and solve for n = number of mols. Then n = grams/molar mass. You know molar mass and n, solve for grams.
