A student investigated the reaction between magnesium ribbon and dilute hydrochloric acid, where the acid acts as the limiting reactant.
With a fixed volume of acid of pH 3, the mass of hydrogen gas produced when the reaction is complete is 0.004 g.
Predict the mass of hydrogen gas produced in the reaction with the same volume of acid of pH 2.
