10.0 g of CaCO(3) on heating gave 4.4 g ...

10.0 g of `CaCO_(3)` on heating gave 4.4 g of `CO_(2)` and x g of CaO. Applying law of conservation of mass calculate the mass of CaO.

Text Solution

Verified by Experts

According to the law
Mass of reactants = mass of product, here
`underset(10 g)(CaCO_(3))rarr underset(4.4 g)(CO_(2))+underset(x)(CaO)`
Hence, x = 10 g - 4.4 g = 5.6 g
Which is mass of CaO.
