Calculate the molecular mass of the following :
(i) `H_(2)O`
(ii) `CO_(2)`
(iii) `CH_(4)`

Text Solution

Verified by Experts

(i) Molecular mass of `H_(2)O`
`=2(1.008 u) + (16.00 u) = 18.016 u` M
(ii) Molecular mass of `CO_(2)`
`=1(12.01 u) + 2(16.00 u) = 44.01 u`
(iii) Molecular mass of `CH_(4)`
`=1(12.01 u) + 4(1.008 u) = 16.042`u
