What mass of protons is required to neutralize the charge of 1.0 g of electrons?
The proton-to-electron mass ratio, μ or β, is simply the rest mass of the proton divided by that of the electron. Because this is a ratio of like-dimensioned physical quantity, it is a dimensionless quantity , a function of the dimensionless physical constants, and has numerical value independent of the system of units, namely:
μ = mp/me = 1836.15267389
Here we have to find the mass of proton required to neutralise 1.0g of electron
Thus 1.01836= 1836 g of proton is required.
