a) How many moles of atoms are in 7.00 g of 13C?
Answer "0.538" mol 13C
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
c) Based on your answer in Part B, how many electrons are in this amount of 13C?
______ electrons
d) Based on your answer in Part B, how many neutrons are in this amount of 13C?
______ neutrons
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.
c) Based on my answer in Part B, there are so many electrons in this amount of 13C that even I can't count them all. It's a carbon party in there!
d) As for the neutrons, they're trying to be cool and neutral, so they're just hanging out, doing their own thing. But I'm not a neutron counter, so I can't give you an exact number.
To find the number of moles of atoms in 7.00 g of 13C, we need to use the molar mass of 13C.
a) First, we find the molar mass of 13C, which is 13.01 g/mol.
b) Next, we divide the given mass (7.00 g) by the molar mass (13.01 g/mol):
7.00 g / 13.01 g/mol = 0.538 mol.
So, there are 0.538 moles of 13C atoms in 7.00 g of 13C.
c) To find the number of electrons in this amount of 13C, we need to multiply the number of moles by Avogadro's number (6.022 × 10^23 electrons/mol):
0.538 mol * 6.022 × 10^23 electrons/mol ≈ 3.24 × 10^23 electrons.
Therefore, there are approximately 3.24 × 10^23 electrons in this amount of 13C.
d) The atomic number of carbon is 6, which means that carbon atoms have 6 protons. The 13C isotope contains 6 protons and 7 neutrons. Since we know the number of 13C atoms is 0.538 mol, we can multiply this by Avogadro's number (6.022 × 10^23 atoms/mol) to find the number of atoms:
0.538 mol * 6.022 × 10^23 atoms/mol ≈ 3.24 × 10^23 atoms.
Therefore, there are approximately 3.24 × 10^23 atoms of 13C in this amount. Since each 13C atom contains 7 neutrons, the number of neutrons is also approximately 3.24 × 10^23.
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
c) from b) ... six electrons per atom
d) from b) ... seven neutrons per atom
