Problem: A sample of N2 O gas has a density of 2.90 g/L at 298 K.What must be the pressure of the gas (in mmHg)?

FREE Expert Solution

We will derive the density from the ideal gas law equation:

PV=nRT

PVV=nRTVP=nRTV

n=mass (m)molar mass (M)

P=mRTMV

mV=gL=density (d)

P (M)=dRTM(M)PMRT=dRTRTd=PMRT
