Explanation:
Answer:
3.34×10³⁰ molecules of C₉H₈O₄
Explanation:
Let's determine the molar mass of aspirin:
C₉H₈O₄ → 12 g/mol . 9 + 1g/mol . 8 + 16g/mol . 4 = 180 g/mol
Let's convert the mass from g to mg → 180 g . 1000 mg/1g = 180000 mg
= 1.8×10⁵ mg
Now, we make a rule of three:
In 1.8×10⁵ mg of aspirin (1 mol) we have 6.02×10²³ molecules
In 100 mg of aspirin, we may have ( 100 . 6.02×10³) / 1.8×10⁵ = 3.34×10³⁰ molecules
