Question

When copper metal is added to silver nitrate in solution , silver metal and copper (2) nitrate are produced. What mass of silver is produced from 100 gram cu

Answer 1

Explanation:

Write the balanced equation:

Cu(s) + 2AgNO3(aq) ==> Cu(NO3)2(aq) + 2Ag(s)

moles Cu present = 100. g Cu x 1 mol Cu/63.55 g = 1.574 moles Cu

mass of Ag produced = 1.574 mol Cu x 2 mol Ag / 1 mol Cu x 107.9 g Ag / mol Ag = 340. g Ag
