molecular mass of H²:
=2×atomic mass of H
=2×1g
=2g
Molecular Mass of O²:
=2×atomic mass of O
=2×16g
=32g
Molecular mass of cl²:
=2×atomic mass of cl
=2×35.5g
=71g
Molecular mass of C²H4:
=2× atomic mass of c+4×atomic mass of H
=2×12g+4×1g
=28g
molecular mass of NH³:
=1×atomic mass of N+3×atomic mass H
=1×14g+3×1g
=17g
Molecular mass of CH3OH:
=1× atomic mass of C+4×atomic mass of H+1×atomic mass of O
=1×12+4×1g31×16g
=32g

the molar mass of
H2 is 2 ×1u=2 u
O2 is 2 ×16u=32u
cl2 is 2 ×35.5u=70u
c2 is 2 x12u =24th
H4 is 4x 1u =4u
NH3 is 1x 14u+3x1u=17th
sorry other questions I have not understand
