g antimony is used as a catalyst in the production of many plastic polyesters. if the plasticis used as a container, some trace amounts of antimony may diffuse into the interior. whileexperimenting, you determine that 44.7μg/lof antimony is present in a batch of fruit juice.at that rate, how many moles of antimony would you expect to find in a gallon of the juice?note that the molecular mass of antimony is 121.76g/mol

Answer:

1.39x10⁻⁶ mol

Explanation:

First we convert the gallon of juice to liters:

  • 1 gallon = 3.785 L

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
