Answer 1

The numbers are messed up, don't copy and paste from khan.

The answer is 100

Explanation:

I took the test

Answer 2

The current density of the solution in
`m^2` is
`11100A/m^2`

Explanation:

One square decimeter is equal to 0.01 square meter, Thus the current density in square meters is

`(111A)/(dm^2) =(111A)/(0.01m^2) =(111)/(0.01)*(A)/(m^2)=\boxed{11100A/m^2}`

11100 Amperes per square meter.
