Electrolysis of a 20% potassium acetate ...

Electrolysis of a 20% potassium acetate solution at 290 K yields, among other things, ethane evolved on the anode according to the equation
`CH_3COO^(-) = C_2H_6 + 2CO_3 + 2e`
The ratio between the molecules of ethane evolved on the anode and those of hydrogen evolved on the cathode is 0.8. Find current yield of ethane.
