Iron reacts with copper (ii) sulfate to produce copper and iron (ii) sulfate. if 5.6 moles of iron react, how many molecules of iron (ii) sulfate will be produced?
1 fe + 1 cuso4 --> 1 cu + 1 feso4

The molecules of Fe formed are 3.37 ₓ10²⁴

Explanation:

The reaction is this one:

Fe + CuSO₄ --> Cu + FeSO₄

And the ratio for the reaction is 1:1

If 5.6 moles of iron react, you will have 5.6 moles of FeSO₄. By the way, you should use NA to calculate the number of molecules.

1 mol has ___ 6.02x10²³

5.6 moles (5.6 x 6.02x10²³) = 3.37 ₓ10²⁴
