Give the answer up to two places of decimal.

The salt ${\mathrm{Na}}_2{\mathrm{HPO}}_4$ is formed when Orthophosphoric acid is reacted with an alkali. Find the equivalent weight of Orthophosphoric acid.

$0.501 \mathrm{g}$ of silver was dissolved in nitric acid and $\mathrm{HCl}$ was added to this solution, $\mathrm{AgCl}$ so formed weighed $0.6655 \mathrm{g}$. If the equivalent weight of chlorine is $35.5$. What will be the equivalent weight of silver?

Give the answer up to two places of decimals.

$5 \mathrm{g}$ of zinc displaced $4.846 \mathrm{g}$ of copper from a copper sulphate solution. If zinc has an equivalent weight of $32.5,$ find the equivalent weight of copper.
