Two acids ${\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_4$ and ${\mathrm{H}}_3\mathrm{P}{\mathrm{O}}_4$ are neutralized separately by the same amount of an alkali when sulphate and hydrogen orthophosphate are formed, respectively. Find the ratio of the masses of ${\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_4$ and ${\mathrm{H}}_3\mathrm{P}{\mathrm{O}}_4$.
