Which of the following statement is true of a proton?
-
The mass of a proton is 1840 times the mass of electron
- the total mass of the protons in a particular nucleus is always half the nuclear size
- The mass of a proton is one - twelfth the molar mass of carbon
- The mass of a proton is 1.0008g
The correct answer is: A
Explanation
The mass of a proton is 1.6726×10−24 g, while the mass of a proton = 1.00727 a . m. u. so OPTION A is correct because the mass of an electron is \(\frac{1}{1840}\) of that of a proton, which is the same as say the mass of a proton is 1840 times the mass of an electron.
