Answer:
Proton: m= 1.6726x10⁻²⁷ kg
Neutron: m= 1.6749x10⁻²⁷ kg
Electron: m= 9.1164x10⁻³¹ kg
Explanation:
We can calculate the mass of a proton, neutron, and electron using the following data:
mass of proton: 1.00728 amu
mass of neutron: 1.00867 amu
mass of electron: 5.49x10⁻⁴ amu
1 amu = 1.66054x10⁻²⁷ kg
Now, the mass of a proton, neutron, and electron in kilograms can be calculated using the next relation:
[tex] m = 1.66054 \cdot 10^{-27} \frac{kg}{amu} \cdot particle's mass (amu) [/tex]
For the proton:
[tex] m = 1.66054 \cdot 10^{-27} \frac{kg}{amu} \cdot 1.00728 amu = 1.6726 \cdot 10^{-27} kg [/tex]
For the neutron:
[tex] m = 1.66054 \cdot 10^{-27} \frac{kg}{amu} \cdot 1.00867 amu = 1.6749 \cdot 10^{-27} kg [/tex]
For the electron:
[tex] m = 1.66054 \cdot 10^{-27} \frac{kg}{amu} \cdot 5.49x10⁻⁴ amu = 9.1164 \cdot 10^{-31} kg [/tex]
I hope it helps you!
