In part B of my question, I was asked calculate the number of atoms in 0.615 mol of 13C (mass number of this Carbon is 13).
I received the correct answer of 3.70E23 atoms.
However, I do not know how to do Part C of my question, which asks "Based on your answer in Part B, how many electrons are in this amount of 13C"?
Similarly, Part D asks "how many neutrons are in this amount of 13C"?
Thank you so much in advance!

You have 3.70E23 atoms and there are 12 electrons/atom so.......
For part D, you have 3.70E23 atoms and there are 7 neutrons/atom so......
Note: 6 potons and 7 neutrons = 13 nucleons = mass number 13

Based on your answer in Part B, how many electrons are in this amount of 13C?
Express your answer numerically in electrons.
=2.50×1024 electrons

Based on your answer in Part B, how many electrons are in this amount of 13C?
Express your answer numerically in electrons.
=2.50×10^24 electrons
