This question will walk you through the process of calculating the
number of molecules present in a sample of a compound with a given
mass and chemical formula. This problem will be solved via the
following sequence of conversions: mass ā moles ā molecules
Consider a dose of Pepto Bismol containing 525 mg of its active
ingredient, bismuth subsalicylate (C7HsBIO4).
Step 2a: Design a problem-solving strategy. Convert the mass given in
milligrams to grams. The molecular formula of bismuth subsalicylate is
C7HsBIO4. What is the molar mass of this compound?
