Question

When copper metal is affed to silver nitrate in solution, silver metal and copper (II) nitrate are produced. Use the balanced equation to answer the question.
How many grams of silver are produced from 4.00 moles of copper?​

Answer 1

Answer:

• Cu(s) + 2AgNO3(aq) → Cu(NO3)2(aq) + 2Ag(s).

Moles Cu present = 100g Cu x 1 mol Cu/63.55g

= 1.574moles Cu

Mass of Ag produced = 1.574mol Cu x 2mol Ag / 1mol Cu x 107.9g Ag/mol Ag

= 340.g Ag
