From the equation :
`3Cu + 8HNO_(3) to 3Cu (NO_(3))_(2) + 4H_(2)O + 2NO` Calculate :
mass of copper needed to react with 63 g of `HNO_(3)`

Explanation

To solve the problem of calculating the mass of copper needed to react with 63 g of HNO₃ based on the given chemical equation, we can follow these steps:

### Step 1: Write down the balanced chemical equation
The balanced chemical equation is:
\[ 3 \text{Cu} + 8 \text{HNO}_3 \rightarrow 3 \text{Cu(NO}_3\text{)}_2 + 4 \text{H}_2\text{O} + 2 \text{NO} \]

### Step 2: Determine the molar masses
- Molar mass of copper (Cu) = 63.5 g/mol
