The percentage composition of nitrogen in the compound would be (aqueous tension at $300 \mathrm{~K}=15 \mathrm{~mm}$ )
228751 A mixture of $\mathrm{CaCl}_2$ and $\mathrm{NaCl}$ weighing $4.44 \mathrm{~g}$ is treated with sodium carbonate solution to precipitate all the calcium ions as calcium carbonate. The calcium carbonate so obtained is heated strongly to set $0.56 \mathrm{~g}$ of $\mathrm{CaO}$. The percentage of $\mathrm{NaCl}$ in the mixture is (atomic mass of $\mathrm{Ca}=40$ )
