Q1

A sample of \(\mathrm{CaCO}_3\) and \(\mathrm{MgCO}_3\) weighed \(2.21 \mathrm{~g}\) is ignited to constant weight of \(1.152 \mathrm{~g}\). The composition of mixture is : (Given molar mass in \(\mathrm{g} \mathrm{mol}^{-1} \mathrm{CaCO}_3: 100, \mathrm{MgCO}_3: 84\) )

a

\(1.187 \mathrm{~g} \mathrm{~CaCO}_3+1.023 \mathrm{~g} \mathrm{~MgCO}_3\)

b

\(1.023 \mathrm{~g} \mathrm{~CaCO}_3+1.187 \mathrm{~g} \mathrm{~MgCO}_3\)

c

\(1.023 \mathrm{~g} \mathrm{~CaCO}_3+1.023 \mathrm{~g} \mathrm{~MgCO}_3\)

d

\(1.187 \mathrm{~g} \mathrm{~CaCO}_3+1.187 \mathrm{~g} \mathrm{~MgCO}_3\)
