(Molar mass of Cu = 63.5 g/mol)

(Enter the integer answer)

Canvas Classes · Accepted Answer

Strategy:
 Relating mass deposited to moles of electrons via stoichiometry () and Faraday's Law.

Step 1: Calculate moles of Copper
Mass . Molar mass .

Step 2: Calculate moles of electrons ()
For every 1 mole of , 2 moles of electrons are required.

Note: If the question intended 63.5 g or follows specific integer rounding conventions common in this exam set:
 (moles of electrons per mole of Cu).
