Determine the molecular mass of water .

Text Solution

Verified by Experts

The molecular formula of water is `H_(2)O`
Atomic mass of H = 1
Atomic mass of O = 16.
`therefore` molecular mass of water = (2 `xx` atomic mass of H ) + (1 `xx` atomic mass of O)
`= 2 xx 1 + 1 xx 16 = 18`.
So , molecular mass of water = 18 amu .
