Asystem of 1610 particles, each of which is either an electron or a proton, has a net charge of −5.376×10^−17 c. how many electrons are in this system? what is the mass of this system?

Number of electrons in the system = 973.

Total mass of the system =

Explanation:

Assumptions:

Given:

Since, the system is comprised of electrons and protons only, therefore,

The net charge on the system can be written in terms of charges on electrons and protons as

Putting the value of (2) in (1), we get,

It is the number of electrons in the system.

Therefore, the number of protons is given by

The total mass of the system is given by

answer: electrons
