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!

  • chemistry -

    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

  • chemistry -

    2.22*10^24

  • chemistry -

    electrons 2.22*10^24 Neutrons 2.59*10^24

  • chemistry -

    1.94*10^24
