Calculate the weight of 60% `H_(2)SO_(4)` required decomposing 50 g of chalk (Calcium carbonate ) .

Text Solution

Verified by Experts

The correct Answer is:
81.67 g
`underset(100g)(CaCO_(3))+underset(98g)(H_(2)SO_(4))rarrCaSO_(4)+H_(2)O+CO_(2)`
`"50 g chalk will required pure "H_(2)SO_(4)=49g`
`therefore" "60%H_(2)SO_(4)" required "=(100)/(60)xx49=81.67g`
