the balanced chemical equation for the reaction of copper (cu) and silver nitrate (agno3) is shown below. cu + 2agno3 → 2ag + cu(no3)2 how many moles of copper must react to form 3.50 mol of ag? 0.175 mol 1.75 mol 7.00 mol 17.0 mol
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, $n_{Cu}=\frac{n_{Ag}}{2}$. Substituting the value of $n_{Ag}$, we get $n_{Cu}=\frac{3.50}{2}=1.75$ mol.
Answer:
1.75 mol
