Calculate the mass of 0.72gram molecule of carbon dioxide `(CO_(2))`

Text Solution

Verified by Experts

Molecular mass of `CO_(2)="Atomic mass of "C+2xx" Atomic mass of O"`
`=(12u+2xx16u)=44u`
Gram molecule mass (Molar mass) of `CO_(2)=44g`
1 gram of molecule of `CO_(2)=44g`
0.72gram molecule of `CO_(2)=((44g))/((1g))xx(0.72g)`=31.68g
