<h3>Further explanation</h3>
Given
1000 C of charge for x grams of copper
Required
Number of charge
Solution
Faraday's Law :

For 1000 C, W = x grams

For 5x grams :

A control group is the group in an experiment that does not receive any sort of change, to then be compared to the other treated objects at the end of the study.
