A stable subatomic particle known by the symbol for "proton"

e elementary charge, p, H+, or 1H+ having a positive electric charge. Its mass is 1,836 times greater than an electron's mass and just a little bit less than that of a neutron (the proton–electron mass ratio). "Nucleons" refers to protons and neutrons together, each of which has a mass of roughly one atomic mass unit (particles present in atomic nuclei).

Each atom. has a nucleus. that contains one or more protons. In order to keep the atomic electrons bound, they offer the central attractive electrostatic force. An element's defining characteristic, known as the atomic number, is the number of protons in the nucleus (represented by the symbol Z)

The concentration after dilution is 1.4%.

We are aware that concentration and volume are related to each other by the formula -

$C_{1}$ $V_{1}$ = $C_{2}$ $V_{2}$ , where we have initial concentration and volume on Left Hand Side and final concentration and volume on Right Hand Side.
