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!
electrons 2.22*10^24 Neutrons 2.59*10^24
2.22*10^24
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.
=2.50×10^24 electrons
1.94*10^24
To find the number of electrons in a given amount of 13C, you need to understand the atomic structure of carbon. Carbon has an atomic number of 6, which means it has 6 protons and 6 electrons. Since the question specifies that you are dealing with 13C, which has a mass number of 13, it means this is a carbon atom with 13 nucleons (protons + neutrons).
In this case, since the question asks about 0.615 mol of 13C, you can use Avogadro's number (6.022 x 10^23) to convert from moles to number of particles.
To find the number of electrons, you can assume that each carbon atom has 6 electrons, based on its atomic number. So, you can multiply the number of carbon atoms (obtained in Part B) by 6 to find the total number of electrons.
Here's the calculation for Part C:
Number of electrons = Number of carbon atoms x 6
= 3.70E23 atoms x 6
= 2.22E24 electrons
So, there are 2.22 x 10^24 electrons in 0.615 mol of 13C.
For Part D, you need to find the number of neutrons in 0.615 mol of 13C. Since the atomic mass of carbon is 12.01 amu and the mass number of 13C is 13, it means there is 1 neutron in each atom of 13C.
Here's the calculation for Part D:
Number of neutrons = Number of carbon atoms x 1
= 3.70E23 atoms x 1
= 3.70E23 neutrons
So, there are 3.70 x 10^23 neutrons in 0.615 mol of 13C.
Based on your answer in Part B, how many electrons are in this amount of 13C?
Express your answer numerically in electrons.
