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 0.854 mol ag? mol cu
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.
