The balanced reaction is:
<span>Cu + 2AgNO3 = 2Ag + Cu(NO3)2
We are givent the amount of silver to be produced. This will be the starting point. Calculations are as follows:
</span><span> 3.50 mol Ag ( 1 mol Cu / 2 mol Ag ) = 1.75 mol Cu
</span>
Therefore, we need 1.75 mol of copper in order to produce 3.50 mol of silver.
Maybe H20 but I’m really not sure
