Question

Calculate the molecular weight H₂, O₂, Cl₂, CO₂, CH₄, C₂H₄, C₂H₄, NH₃, CH₃OH.

Answer 1

Molecular weight of H₂ = 2 × 1 = 2 u 

Molecular weight of O₂ = 2 × 16 = 32 u 

Molecular weight of Cl₂ = 2 × 35.5 = 71 U 

Molecular weight of CO₂ = 12 + 2 × 16 = 44 u 

Molecular weight of CH₄ = 12 + 4 × 1 = 16 u 

Molecular weight of C₂H₆ = 2 × 12 + 6 × 1= 30 u

Molecular weight of C₂H₄ = 2 × 12 + 4 × 1= 28 u 

Molecular weight of NH₃ = 14 + 3 × 1 = 17 u 

Molecular weight of CH₃OH = 12 + 4 × 1 + 16 = 32 u
