Question

The net charge of 3 mol of protons is

a) 4.81×10 4 C .
b) 3.00 C
c) 4.81×10 −19 C
d) 2.89×10 5 C

Answer 1

The charge of 1 mole of proton is equivalent to 1.60217656x10^-19 coulombs. This is also called an elementary charge. Multiply that by 3 to get the net charge of three moles of protons.

Charge of 3 mol protons = 3 x 1.60217656x10^-19 = 4.81x10^-19 coloumbs

So the answer is c) 4.81×10 −19 C
