How many atoms of oxygen are present in 50 g of `CaCO_(3)`

Text Solution

Verified by Experts

Molecular mass of `CaCO_(3)=40+12+3x 16`
`=100g`
Atoms of oxygen present in 100g of `CaCO=3x 6.022x10^(23)` atoms.
Atoms of oxygen present in 50g of `CaCo`
`={(3x6.022xx10^(23))//100}xx50` atoms
`=9.033x 10^(23)`
