Calculate the mass of 60%H_(2)SO_(4) required to decompose 50 g of cha – InterviewSolution

1.	Calculate the mass of 60%H_(2)SO_(4) required to decompose 50 g of chalk (calcium carbonate).
Answer» SOLUTION :`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`
