a) How many moles of atoms are in 7.00 g of 13C?
Answer "0.538" mol 13C
yes, that's right
b) Based on your answer in Part A, calculate the number of atoms in this amount of 13C?
Answer "3.24×10^23" 13C atom
Yes, that's right.
c) Based on your answer in Part B, how many electrons are in this amount of 13C?
______ electrons
You hve 3.24E23 atoms C13 and there are 6 electrons in each atom. How do I know there are 6 electrons/atom. That's the atomic number of C in the periodic table and the atomic number is 6
d) Based on your answer in Part B, how many neutrons are in this amount of 13C?
______ neutrons
You have 7 neutrons in each C13 atom. You know protons + neutrons = mass number of 6+? = 13

They are asking for how many electrons and neutrons are in 3.24x10^23 atoms not in a single carbon atom.
Therefore,
Part C would be 1.944x10^24
Part D would be 2.268x10^24
In order to get those, you would take 6 or 7 whatever the amount of the electrons or neutrons you are trying to find and you multiply that by 3.24x10^23.
