Question #14344
How many grams of Cu and what volume of O2 gas will be obtained if 18.4 ampere electric current is passed through the electrolytic cell of CuSO4for 1 hour and 42 minutes between graphite electrodes at 208 K temperature and 1 bar pressure?
(Cu=63.5u O=16u) How to calculate?
Expert's answer
m = k · Q,
Q = I · t.

m=Mw/96500 * I *

m(Cu)=63.5/96500 *18,4*6120=74.099



V=(37.34/32)*8.31*208 /105=19.21 L
