Question

Calculate the molecular masses of
H2, CO2
​

Answer 1

Answer:

Moleculer mass of H

2

=2×Atomic mass of H

=2×1μ=2μ

Moleculer mass of O

2

=2×Atomic mass of O

=2×16μ=32μ

Moleculer mass of Cl

2

=2×Atomic mass of Cl

=2×35.5μ=71μ

Moleculer mass of CO

2

=Atomic mass of C+Atomic mass of O

=(12+32)μ=44μ

Similarly,

Molecular mass of CH

4

12+(4×1)=12+4=16μ

Molecular mass of C

2

H

6

24+6=30μ

Molecular mass of NH

3

14+3=17μ

Molecular mass of CH

3

OH

12+3+16+1=32μ

Answer 2

Answer:

Molecular mass of H2= 2× Atomic mass of H = 2×1 =2 u

therefore the molecular mass of H2 is 2 u .

molecular mass of CO2 = Atomic mass of C + Atomic mass of O = ( 12+32) u = 44 u

therefore the molecular mass of CO2 is 44 u
