1) The molar mass of aspirin would be 180 g/mol.

From the chemical formula, C9H8O4

Molar mass = (9 x 12) + (8 x 1) + (4 x 16)

= 180 g/mol

2) Mole = mass/molar mass.

Number of moles of aspirin in a single tablet with 325 mg aspiring = 0.325/180

= 0.0018 moles

3) 2 tablets of aspirin makes a dose for adults. if four doses are taken per day, that would be a total of 8 tablets.

Total aspirin contents in 8 tablets = 325 mg x 8

= 2600 mg or 2.6 g

Mole of 2.6 g aspirin = 2.6/180

= 0.0144 moles.
