Sample a is a brand of supplement that contains iron in the form of 324mg ferrous gluconate c12h24feo14 per tablet. what is the amount of elemental iron in one table of sample a?

Amount of elemental iron in sample A is 0.0405g.

Explanation:

Molar mass of C = 12 g/mol

Molar mass of H = 1 g/mol

Molar mass of Fe = 56 g/mol

Molar mass of O = 16 g/mol

So, molar mass of ferrous gluconate =

So number of mole of ferrous gluconate in 324 mg =

(number of moles = )

As  1 mol of ferrous gluconate contains 1 mol of Fe therefore of ferrous gluconate contain of Fe.

So amount of elemental iron in sample A =

answer: c.
