A sample of $\displaystyle \mathrm{CaCO}_3$ and $\displaystyle \mathrm{MgCO}_3$ weighed $\displaystyle 2.21$ g is ignited to constant weight of $\displaystyle 1.152$ g . The composition of mixture is :
(Given molar mass in $\displaystyle \mathrm{g} \mathrm{mol}^{-1} \mathrm{CaCO}_3: 100, \mathrm{MgCO}_3: 84$ )
Official answer
From NTA’s final answer key for this paper.
(2)
$\displaystyle 1.187 \mathrm{~g} \mathrm{CaCO}_3+1.023 \mathrm{~g} \mathrm{MgCO}_3$
