Question

The density of a gas depends on its molar mass. Under the same conditions, gases with molar masses less than air will float, while those with molar masses greater than the molar mass of air will sink in air. Air has the equivalent of a molar mass of 29 g/mol. How do you think that value was obtained? Water has a density of about 1 g/mL at room conditions. Each air molecule has approximately 10 diameters in each direction (x, y, and z). Estimate the density of air at room conditions.

Step 1

This value was likely obtained by calculating the average molar mass of the components of air, which include nitrogen, oxygen, carbon dioxide, and other trace gases. Show more…
