How do you find the number of moles of copper in copper gluconate? In my experiment I used 1.4 g of copper gluconate, and ended up with 0.1 g of copper.

0.0016 moles of copper are present in copper gluconate

Explanation:

The number of moles is defined as the ratio of the mass of a substance to its molar mass.

The equation used is:

......(1)

Given mass of copper = 0.1 g

Molar mass of copper = 63.55 g/mol

Plugging values in equation 1:

Hence, 0.0016 moles of copper are present in copper gluconate

i'm assuming that the correct answer is indeed the first one/ "a"..
