Answer

Explanation:

Step1: Identify mole - ratio

From the balanced equation $Cu + 2AgNO_3\rightarrow2Ag+Cu(NO_3)2$, the mole - ratio of $Cu$ to $Ag$ is $n{Cu}:n_{Ag}=1:2$.

Step2: Calculate moles of Cu

We know $n_{Ag} = 3.50$ mol. Using the mole - ratio, $n_{Cu}=\frac{n_{Ag}}{2}$. Substitute $n_{Ag}=3.50$ mol into the formula: $n_{Cu}=\frac{3.50}{2}=1.75$ mol.

Answer:

1.75 mol
