Question

find the molecular mass of oxygen , water ,C2H6​

Answer 1

Answer:

Molecular mass of H2 = 2 u.

Molecular mass of O2= 32 u.

Molecular mass of Cl2 = 71 u.

Molecular mass of CO2 = 44 u.

Molecular mass of CH4 = 16 u.

Molecular mass of C2H6 = 30 u.

Molecular mass of C2H4 = 28 u.

Answer 2

Answer:

Mass of O2 = 2 ×16 = 32 amu

Mass of H2O = 2 ×1 + 16 = 18 amu

Mass of C2H6 = 2× 14 + 1×6 = 34 amu
