What is the density of nitrogen gas at a pressure of 755 Torr and a temperature of 26.0°C?
What is the density of nitrogen gas at a pressure of 755 Torr and a temperature of 26.0°C? I need a formula too if you guys wouldn't mind...
I know that Density = mass/volume but I am not sure how to solve this problem.

Ideal gas law: PV = nRT, so the number of moles is n = PV/RT
mass = moles * molecular weight so mass = PV(MW)/RT
Density = mass / Volume so D = PV(MW)/RTV
D = P(MW)/RT
Because of the constant R, the temperature must be in Kelvin and the Pressure must be in atm
755 torr = (755/750) atm
26 C = 273 + 26 K
