Answer:
Proton: m= 1.6726x10⁻²⁷ kg
Neutron: m= 1.6749x10⁻²⁷ kg
Electron: m= 9.1164x10⁻³¹ kg
Explanation:
<u>We can calculate the mass of a proton, neutron, and electron using the following data:</u>
<em>mass of proton</em>: 1.00728 amu
<em>mass of neutron</em>: 1.00867 amu
<em>mass of electron</em>: 5.49x10⁻⁴ amu
<em>1 amu</em> = 1.66054x10⁻²⁷ kg
Now, the mass of a proton, neutron, and electron in kilograms can be calculated using the next relation:
![m = 1.66054 \cdot 10^{-27} \frac{kg}{amu} \cdot particle's mass (amu)](https://tex.z-dn.net/?f=%20m%20%3D%201.66054%20%5Ccdot%2010%5E%7B-27%7D%20%5Cfrac%7Bkg%7D%7Bamu%7D%20%5Ccdot%20particle%27s%20mass%20%28amu%29%20)
For the proton:
![m = 1.66054 \cdot 10^{-27} \frac{kg}{amu} \cdot 1.00728 amu = 1.6726 \cdot 10^{-27} kg](https://tex.z-dn.net/?f=%20m%20%3D%201.66054%20%5Ccdot%2010%5E%7B-27%7D%20%5Cfrac%7Bkg%7D%7Bamu%7D%20%5Ccdot%201.00728%20amu%20%3D%201.6726%20%5Ccdot%2010%5E%7B-27%7D%20kg%20)
For the neutron:
![m = 1.66054 \cdot 10^{-27} \frac{kg}{amu} \cdot 1.00867 amu = 1.6749 \cdot 10^{-27} kg](https://tex.z-dn.net/?f=%20m%20%3D%201.66054%20%5Ccdot%2010%5E%7B-27%7D%20%5Cfrac%7Bkg%7D%7Bamu%7D%20%5Ccdot%201.00867%20amu%20%3D%201.6749%20%5Ccdot%2010%5E%7B-27%7D%20kg%20)
For the electron:
