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

Explanation

Molecular mass of `CO_(2)` = Atomic mass of C + 2 x Atomic mass of O = (12 u + 2 x 16 u) = 44 u
Gram molecular mass of `CO_(2) = 44 g`
1 gram molecule of
`CO_(2) = 44 g`
1 gram molecule of `CO_(2) = 44 g`
0.72 gram molecule of `CO_(2) = 44/1 xx 0.72 = 31.68 g`
