This question we're told that our current is equal to 1 million amps, which is equal to 10 to 6th amps or 10 to the 6th 2 oms per second.
00:16
Our time is 2 hours.
00:21
Let's convert this to seconds.
00:23
So 1 hour, 60 minutes, and 1 minute, 60 seconds.
00:32
And this is going to give us 7 ,200 seconds.

The equivalent weight for aluminum, we have 27 grams per mole, is the mass of aluminum.
00:56
And it's going to form aluminum 3 plus.
01:00
So this would be equal to 9 grams per mole of electron.
01:07
And then we can calculate the.....
