027 (part 1 of 3) 10.0 points

Copper reacts with silver nitrate through single

replacement. If 3.03 g of silver are produced

from the reaction, how much copper(II)

nitrate is also produced?

Answer in units of mol.

028 (part 2 of 3) 10.0 points

How much Cu is required in this reaction?

Answer in units of mol.

029 (part 3 of 3) 10.0 points

Howmuch AgNO3 is required in this reaction?

Answer in units of mol.

Answer 1

The equation for the reaction is  Cu + 2AgNO₃ ---> Cu(NO₃)₂ + 2Ag

 

The molecular mass of silver is 107.87, so 3.03 grams is 3.03/107.87 = 0.028 mol.

 

There is 1 mol of copper nitrate produced for every 2 mol of silver, so 0.014 mol copper nitrate is produced.

 

Similarly, 014 mol copper and 0.028 mol of silver nitrate are required.
