1) Calculate the total pressure (in atm) of a mixture of 0.0270 mol of helium, He, and 0.0200 mol of oxygen, O2, in a 4-L flask at 20°C. Assume ideal gas behavior.

2) At what temperature does the rms speed of O2 molecules equal 601 m/s?

3) Pyruvic acid, HC3H3O3, is involved in cell metabolism. It can be assayed for (that is, the amount of it determined) by using a yeast enzyme. The enzyme makes the following reaction go to completion.

HC3H3O3(aq) → C2H4O(aq) + CO2(g)

If a sample containing pyruvic acid gives 22.4 mL of carbon dioxide gas, CO2, at 349 mmHg and 30°C, how many grams of pyruvic acid are there in the sample?
