Question

An electrolysis experiment was run for 17.5 minutes at an average current of 191 milliamps (mA). The mass lost by the copper anode was 0.0679 grams.
a) Calculate the number of coloumbs transferred. (coloumb=ampsxsec)
b) Calculate the moles of copper lost from the anode.
c) Calculate the moles of electrons transferred. The reaction at the copper anode is: Cu(s)-->Cu^2+(aq)+2e^-.
