Question 4

An analyst investigates the reaction between excess calcium carbonate chips and a fixed volume of dilute nitric acid, which acts as the limiting reactant.

Using nitric acid with a pH of 4.0, the total mass of carbon dioxide gas collected when the reaction goes to completion is 0.15 mg.

Determine the mass of carbon dioxide gas that would be produced if the reaction were repeated under identical conditions but using the same volume of nitric acid with a pH of 1.0.
