In the following reaction, how many grams of silver can be produced from 49.1 g copper?
notsponge [240]

166.4 g Ag grams of silver can be produced from 49.1 g of copper.

<h3>What is a mole?</h3>

A mole is a very important unit of measurement that chemists use. A mole of something means you have 602,214,076,000,000,000,000,000 of that thing, like how having a dozen eggs means you have twelve eggs.

1 mol Cu + 2 mol AgNO_3 → 2 mol Ag + 1 mol Cu(NO3)2

63.55 g Cu —> 2 x 107.688 g Ag

63.55 g Cu gives 215.376 g of Ag

So, 49.1 g Cu —> \frac{215.376 g X 49.1 g}{63.55 g}

= 166.4 g Ag

Hence, 166.4 g Ag grams of silver can be produced from 49.1 g of copper.
