Answer:
1.39x10⁻⁶ mol
Step-by-step explanation:
First we convert the gallon of juice to liters:
Then we calculate the mass of antimony that would be in 3.785 L, using the given concentration:
- 44.7 μg/L * 3.785 L = 169.2 μg
Then we convert mass into moles, using the molecular mass:
- 169.2 μg ÷ 121.76 μg/μmol = 1.39 μmol
Finally we convert μmol into mol:
- 1.39 μmol = 1.39x10⁻⁶ mol
