Question

calculate the molecular mases of c2h6, c2h4 and cl2​

Answer 1

Answer:

C2 H6 = 30; C2 H4 = 28; Cl 2 = 71

Explanation:

C = Carbon, atomic mass = 12

H =   Hydrogen, atomic mass = 1

Cl= Chlorine, atomic mass = 35.5

Molecular mass

C2 H6 = 2 x 12 + 6 x 1 = 24+6 = 30

C2 H4 = 2 x 12 + 4 x 1 = 24+4 = 28

Cl 2 = 2 x 35.5 = 71

Answer 2

Answer:

C2H6 = 12×2+6×1= 24+6=30g/mol

C2H4= 12×2+4×1= 24+4=28g/mol

Cl2= 2×35.5=71g/mol
