Find the molar mass of C2H2 acetylene.
Molar mass characterizes a substance as the ratio of the mass of a substance to the number of moles of this substance, that is, the mass of one mole of a substance.
The molar masses of complex molecules can be determined by summing the molar masses of their constituent elements.
M (C2H2) = 2 × 12 + 2 × 1 = 24 + 2 = 26 g / mol.
This means that the molar mass of acetylene is 26 g / mol.
