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

Text Solution

Verified by Experts

`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
