Following on from Morpheus I have seen five straight substitution questions from you within the last two hours and ten over the last two days.
I have already passed my degree. You need to question your own current approach to study.

1 Ampere = 1 Coulomb (quantity of elementary charge) per second.
(a) .36 Amperes = 10.8 Coulombs/"x" seconds
X = 10.8C/.36A = 30 seconds
1 Coulomb = 6.241×10^18 elementary charges
10.8 Coulombs × 6.241 × 10^18 e/C = 6.74 × 10^19 elementary charges.
