Question:
How many molecules of aspirin C9H804 are there in 100.0 MG tablets of aspirin
Answer:
The number of molecules of aspirin that are in 100.0 mg tablets of aspirin is 3.34 × 10²⁰ molecules
First, we will determine the number of moles of aspirin present in the 100.0 mg tablets of aspirin.
Using the formula
Molar mass of aspirin = 180.158 g/mol
From the question
Mass of aspirin = 100.0 mg = 0.1 g
∴ Number of moles of aspirin =
Number of moles of aspirin = 5.55068 × 10⁻⁴ mole
Now, for the number of molecules of aspirin
Number of molecules = Number of moles × Avogadro’s constant
∴ Number of molecules of aspirin = 5.55068 × 10⁻⁴ × 6.022 × 10²³
Number of molecules of aspirin = 3.34 × 10²⁰ molecules
Hence, the number of molecules of aspirin that are in 100.0 mg tablets of aspirin is 3.34 × 10²⁰ molecules
