The molar mass is the sum of all the atoms present in one mole of a compound. Since the molecular formula of aspirin is C

Carbon (9 atoms) = 12x9 = 108

Hydrogen (8 atoms) = 1x8 = 8

Oxygen (4 atoms) = 16x4 = 64

To obtain the molar mass of aspirin, simply add up all the values given above;

Molar mass of aspirin = C+H+O

= 108+8+64

= 180

Thus, the molar mass of aspirin is 180 g/mol.

_{9}H_{8}O_{4}, we need to add up the atomic weights of all the elements present in it:Carbon (9 atoms) = 12x9 = 108

Hydrogen (8 atoms) = 1x8 = 8

Oxygen (4 atoms) = 16x4 = 64

To obtain the molar mass of aspirin, simply add up all the values given above;

Molar mass of aspirin = C+H+O

= 108+8+64

= 180

Thus, the molar mass of aspirin is 180 g/mol.
