Answer 2

Answer:

a-)

Moleculer mass of O2

=2×Atomic mass of O

=2×16μ=32μ

b-) 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

c-) Molecular mass of NH3

14+3=17μ

Molecular mass of CH 3

OH 12+3+16+1=32μ

d-) Molecular mass of CH

4

12+(4×1)=12+4=16μ

Molecular mass of C

2

H

6

24+6=30μ
