Calculate how much lime will be obtained by heating 500g of lime stone of 50% purity? [Ca=40, C=12, O=16]

Answer»

SOLUTION :`underset(100g)(CaCO_(3 to underset(50g)(CAO)+CO_(2)`
Amount of PURE `CaCO_(3)` in 500mg of impure lime stone`=(50times100)/(100)=250G`
`therefore250g` of `CaCO_(3)` produces `(56times250)/(100)g=14g` of CaO
