Answer

Answer:

0.427

Explanation:

Step1: Identify mole - ratio

From the equation $Cu + 2AgNO_3\rightarrow2Ag + Cu(NO_3)_2$, the mole - ratio of $Cu$ to $Ag$ is 1:2.

Step2: Calculate moles of Cu

Let $n_{Cu}$ be the moles of $Cu$ and $n_{Ag}$ be the moles of $Ag$. We know $n_{Ag}=0.854$ mol. Using the mole - ratio $\frac{n_{Cu}}{n_{Ag}}=\frac{1}{2}$, so $n_{Cu}=\frac{n_{Ag}}{2}=\frac{0.854}{2}=0.427$ mol.
