Answer:

Molar mass of acetylene = 26.016 g/mol

Explanation:

Molar mass:

molar mass of substance is sum of the atomic weight of individual atoms of element that combine to make the substance.

Molar mass of acetylene:

Atomic weight of carbon = 12 amu

Atomic weight of hydrogen = 1.008 amu

There are two hydrogen and two carbon atom in acetylene.

Molar mass = 12×2 + 1.008 ×2

Molar mass = 24 + 2.016

Molar mass = 26.016 g/mol
