Problem
A hospital keeps single-dose vials that each contain 5.00 grains of acetylsalicylic acid (aspirin), whose molecular formula is C9H8O4. (1 grain = 64.8 mg.) The vial label lists the molar mass of acetylsalicylic acid as 180.2 g mol^−1.
Answer the following questions. Show all reasoning and include units throughout.
(a) Calculate the mass of acetylsalicylic acid in one vial expressed in grams.
(b) Determine the amount (in moles) of acetylsalicylic acid present in the vial.
(c) Find the number of acetylsalicylic acid molecules contained in the vial.
(d) Compute the total number of carbon atoms delivered to a patient who receives the entire contents of one vial.
