Calculate the molecular masses of H2,O2,...

Calculate the molecular masses of `H_2,O_2,Cl_2, CO_2,CH_4,C_2H_4,NH_3,CH_3OH`.

Text Solution

Verified by Experts

Molecular mass of `CH_(3)OH`
= Atomic mass of `C + 3 xx` Atomic mass of H + Atomic mass of O + Atomic mass of H
= `12 u + 3 xx 1u + 16 u xx 1u`
`= 12 u + 3u + 16 u + 1u`
=32 u
