Total charge Q = I.t, where I is the current flowing and t is the time for which current flows.
So Q = 1x60 = 60C
Now, Q = n.e, where n is the number of electrons and e is the charge of an electron.
Charge on an electron = 1.6 x 10^-19 C
So n = Q/e
= 60/ (1.6 x 10^-19)
= 60/1.6 x 10^19
= 37.5 x 10^19
= 3.75 x 10^20
