Estimate the density of air

If we approximate the atmosphere to be 79% nitrogen (N_2) by volume and 21% oxygen (O_2), estimate the density of air (kg/m^3) at STP conditions (0 degrees C, 1 atm)

Solution Preview

Remember 1 mole of ideal gas occupies 22.4L at STP conditions.
Molecular weight of O2 = 32(g/mol)
Molecular ...
