Answer:
1.55x10⁻⁵ moles does the patien take each day
Explanation:
Let's find out the molar mass of ibuprofen, in first place.
C₁₃H₁₈O₂
C = 12 g . 13 = 156
H = 1 g . 18 = 18
O = 16 g. 2 = 32
156 + 18 + 32 = 206 g/mol
In 1 mol of ibuprofen, we have 206 grams of compound.
Mass of compound / Molar mass = Moles of compound
Now, let's convert mg to g
3.2 mg / 1000 = 3.2x10⁻³ g
3.2x10⁻³ g / 206 g/m = 1.55x10⁻⁵ moles
You can say 1.55x10⁻⁵ moles
1.55x10⁻⁵ moles . 1000 = 0.015 mmoles
1.55x10⁻⁵ moles . 1x10⁶ = 15.5 μmoles
