Problem

How many millilitre of 0.5 M H2SO4\text{H}_2\text{SO}_4 are needed to dissolve 0.5 g of copper II carbonate?
Intuitive explanation

This is a stoichiometry problem where you need to connect mass of solid reactant to volume of solution. First, convert the copper II carbonate mass to moles using its molar mass, then use the balanced chemical equation to find the mole ratio between CuCO3\text{CuCO}_3 and H2SO4\text{H}_2\text{SO}_4. Finally, use molarity (M=mol/LM = \text{mol}/\text{L}) to convert moles of acid needed into the volume you're looking for.
