To calculate the mass of copper nitrate obtained by treating 6.4 g of copper with excess concentrated nitric acid, we can follow these steps: ### Step 1: Write the Balanced Chemical Equation The reaction between copper (Cu) and concentrated nitric acid (HNO3) can be represented as: \[ \text{Cu} + 4 \text{HNO}_3 \rightarrow \text{Cu(NO}_3\text{)}_2 + 2 \text{H}_2\text{O} + 2 \text{NO}_2 \] This equation shows that 1 mole of copper reacts with 4 moles of nitric acid to produce 1 mole of copper nitrate. ...
