The first thing we need to remember is that:

We have 7.54g of CuCl2 so we need to express this amount in moles dividing by the molar mass of CuCl2.

This is:

And, also remember that 65.0mL equals 0.065L.

Now, replacing in the molarity equation:

Thus the answer is 0.862M.

How many grams of the excess reactant remain assuming the reaction goes to completion and that you start with 15.5g of na2s and
tangare [24]
The reaction between Na2S and CuSO4 will give us the balanced chemical reaction of,
                                     Na2S + CUSO4 --> Na2SO4 + CuS
This means that for every 78g of Na2S, there needs to be 159.6 g of CuSO4. The ratio is equal to 0.4887 of Na2S: 1 of CuSO4. Thus, for every 12.1g of CuSO4, we need only 5.91 g of Na2S. Thus, there is an excess of 9.58 g of Na2S. The answer is letter C.
