How many moles of Ag can be produced if 350. g of Cu are reacted with excess AgNO3 according to the equation Cu(s) + 2AgNO3(aq)
Ksju [112]
Hello.

balance the equation first 
<span>Cu + 2AgNO3 ----> [2Ag] + Cu(NO3)2 
</span>

<span>Now set up the equation </span>
<span>350gCu*(1molCu/ 63.546g Cu) * (2molAg/1molCu) * (107.8682g Ag/1molAg)
 </span>

<span>Cancel out 1molCu with 1molCu, and cancel out 2molAg with 1molAg (it still remains 2mol Ag) </span>

<span>You are left with </span>
<span>350gCu*(1/63.546g Cu)*(2Ag/1)* (107.8682g Ag/1) 
</span>

<span>350gCu*1*2*107.8682= 75507.74g 
</span>

<span>now divide 75507.74g by 63.546g 
</span>
<span>you get [1188.2374972460896g Ag]
</span>
