The reaction `An+CuSO_4toZnSO_4` goes completely to the right. In an experiment, 10.0 g of Zn was added to 200 " mL of " `CuSO_4` solution. After all the Cu was precipitated, it was found that not all the Zn had dissolved. After filtration, the total weight of the solid at the end of the reaction was 9.810 g. Calculate.
(a). The weight of copper deposited and,
(b). Molarity of `CuSO_4` in the original solution.

Explanation

To solve the problem, we will break it down into two parts: calculating the weight of copper deposited and finding the molarity of the original CuSO₄ solution.

### Step-by-Step Solution

**Step 1: Write the balanced chemical equation.**
The reaction between zinc and copper sulfate can be represented as:
\[ \text{Zn} + \text{CuSO}_4 \rightarrow \text{ZnSO}_4 + \text{Cu} \]
