A copper voltameter deposits 2.00 g of Cu when a current of 2.0 A is passed for 1.0 h . What mass of Cu will be deposited if the current is 3.0 A for 40 min in the same voltameter?
Text Solution
Verified by ExpertsThe correct answer is:
A
Mass deposited œ charge
(Faraday's 1st law). The two cases have equal 
:
, thus, same 
in the same voltameter.
