Answer : The total electric charge of electrons is, 
Explanation:
Answer : The number of electrons transferred are, 
Explanation :
First we have to calculate the number of electrons.
Number of electrons = 
Mass of 1 electron = 
Total mass of electron = 2.5 kg
Number of electrons = 
Number of electrons = 
Now we have to calculate the total electric charge of electrons.
Formula used :

where,
n = number of electrons transferred = 
Q = charge on electrons = ?
e = charge on 1 electron = 
Now put all the given values in the above formula, we get:


Thus, the total electric charge of electrons is,
