Answer:
0.004 6949 18602 2713 mole
<span>Moles of solid copper used in reaction, using molar mass:
1 gram Cu @ 63.55 g/mol = 0.0157 moles Cu
(f) Moles of solid silver produced in reaction , using molar mass:
3.395g Ag @ 107.87 g/mol = 0.317 moles of Ag
Write the net ionic equation for the reaction between, using your mole values:
0.0157 Cu (s) & 0.317 Ag+ --> 0.0157 Cu+2 & 0.317 Ag (s)
Convert to whole number ratio, by dividing by the smaller :
0.0157 moles Cu / 0.057 = 1 mole Cu
0.317 moles Ag+ / 0.157 = 2 moles Ag
and rewrite the equation using the whole number ratio:
1 Cu (s) & 2 Ag+ --> 1 Cu+2 & 2 Ag (s)</span>
