Question

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

Answer 1

The molecules of Fe formed are 3.37 ₓ10²⁴

Step-by-step 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
