How many coulombs are represented by these amounts of electr

How many coulombs are represented by these amounts of electrons?

a- 6.482x10^17

c- 2.46x10^19

Ans)

We know that the a electron have charge of 1.6 × 10¹⁹ C

e =1.6 × 10¹⁹ C

a) No of coulombs =6.482*10^17*1.6*10^-19=0.1037 coulombs

c) No of coulombs =2.46*10^19*1.6*10^-19=3.936 coulombs
