d) from b) ... seven neutrons per atom
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
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.
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.
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.
