I tried to use the Q=It equation but it doesn't work because all I have is 96485C and the moles in the end. Is there another equation or something that I am missing? I tried googling but they only had the Q=It equation. If you know something that would help, please post!

The nitrate salt of an unknown metal is dissolved in water and electrolysed. The unknown metal is
deposited on the cathode, which increases in mass by 1.79 g, and 6.34 g of the copper anode
dissolves into solution.
Which one of the following is the unknown metal?
A Sr
B Ge
C Al
D Na
E Cu

6.34 g of the copper anode dissolves into solution.

This gives Q.

Now you have to do some guesswork - assume n = 1, 2, 3... and calculate molar mass of the metal in question for each case.

Faraday contant is equal to one mole of electrons
