What mass of CaO is formed by heating 50...

What mass of `CaO` is formed by heating `50g CaCO_(3)` in air ?
[molar mass : `CaCO_(3) = 100, CaO = 56]` .

Text Solution

Verified by Experts

`CaCO_(3)(s)rarrCaO(s)+CO_(2)(g)`
`50gm`
`=(50)/(100)mol`
`=(1)/(2)"mol" " "(1)/(2)"mol"`
`= (1)/(2) xx 56 = 28gm` .
