how many grams of copper required to produce 200g of copper (II) sulfate?

Question

2Cu + S2 ------ 2CuS

Im stuck

Answer 1

Well, for a start your equation shows copper(II) sulphide, not sulphate, and your equation is wrong even then. That makes a bit of a difference!

Let us imagine that you've got the formula right, but the name wrong.

The equation is simply Cu + S ---> CuS

Then 64g will give (64+32)g.

Thus 64g will give 96g.

So 64 x (200/96)g of Cu will give 200g of product.
