5. i) Using the ideal gas law, find the number of air molecules per unit volume in air at 25 ◦ C and atmospheric pressure.
ii) Assuming air to be 80 % N2 and 20 % O2, show that the average molecular weight of dry air is around 28.8 grams per mol.
iii) Combine this with the result from part i) to calculate the density of dry air at 25 ◦ C.

The ideal gas law describes the relationship among the volume of an ideal gas (V), its pressure (P), its absolute temperature (T), and number of moles (n): PV=nRT Under standard conditions, the ideal gas law does a good job of approximating these properties for any gas. However, the ideal gas law does not account for all the properties of real gases such as intermolecular attraction and molecular volume, which become more pronounced at low temperatures and high pressures. The van...
