a.
density=mass/volume
you know the molar volume, (one mole NO2 is 46grams)
gas constant: 0.082057338 Latm/Kmol
So volume of one mole is
V=nRT/P=1*.083*(273+35)/.970 calculate that.
density=46/volume
b. R=62.363577 L Torr K−1 mol−1
b. n=PV/RT=685*.875/62.4*(273+35)
figure that out.
molmass=2.5/n
(A) calculate the density of NO2 gas at 0.970atm and 35 Celsius.
(B) calculate the molar mass of a gas if 2.50g occupies 0.875L at 685torr and 35 Celsius.
Answers are 1.77g/L
80.1g/mol
