A reaction at 4.0°C evolves 442.mmol of carbon dioxide gas. Calculate the volume of carbon dioxide gas that is collected. You can assume the pressure in the room is exactly1atm. Round your answer to 3 significant digits.

A reaction at 19.0°C evolves 483.mmol of carbon dioxide gas. Calculate the volume of carbon dioxide gas that is collected. You can assume the pressure in the room is exactly 1atm . Be sure your answer has the correct number of significant digits.

Please help me how to solve this question. Thank you very much.

When two cotton plugs. one moistened with ammonia and the other with hydrochloric acid, are simultaneously inserted into opposite ends of a glass tube that is 87.0 cm long, a white 1111g of NH4Cl forms where gaseous NH3 and gaseous HC1 first come into contact. NH3(g)+HCl(g)NH4Cl(s) At approximately what distance from the ammonia moistened plug does this occur? (Hint: Calculate the rates of diffusion for both NH3 and HCI, and find out how much faster NH3 diffuses than HCI.)
