Question

calculate the total charge in coulombs carried by 0.2 mol of electrons​

Answer 1

Answer:

Explanation:

molarity=n/v

so n=no. of electrons

v=1 litre solution

molarity=0.2 mol

so molarity=n/v

    0.2=n/1

so no. of electrons=0.2

Q=ne

Q=0.2*1.6*10^-10

charge of electron=0.32*10^-19 coulomb
