Question

1. Aspirin, also known as acetylsalicylic acid (C9H8O4) is a medication, often used to relieve minor aches and pains and reduce fever. Each tablet contains 325 mg of aspirin, and a typical adult dose is two tablets every four hours.
• Determine the molar mass of aspirin. Show all steps to find the answer.
• Calculate the number of moles of aspirin in a single tablet. Show all steps to find the answer.
• Calculate the number of moles of aspirin that an adult would have taken if she took four doses of aspirin in one day. Show all steps to find the answer.

Answer 1

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.
