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!

**DrBob222**, Sunday, September 16, 2012 at 2:15pmYou 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

Express your answer numerically in electrons.

=2.50×1024 electrons
