Copper and Silver Nitrate Reaction: Calculate Copper Moles
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 : The correct option is, 1.75 mol
Solution:
Given,
Moles of silver = 3.50 mol
The balanced chemical reaction is:
Cu + 2AgNO₃ → 2Ag + Cu(NO₃)₂
From the balanced chemical reaction, we conclude that:
2 moles of silver obtained from 1 mole of copper
So, 3.50 moles of silver obtained from 3.50 / 2 = 1.75 moles of copper
Therefore, 1.75 moles of copper must react to form 3.50 moles of silver.
