The molecular mass for chlorine is not an integer multiple of the molecular mass of hydrogen but is about 35.5 times the molecular mass of hydrogen.This is primarily because
A)the proton and neutron have different masses.
B)there are different isotopes of chlorine.
C)of the binding energy of the chlorine nucleus.
D)the chlorine nucleus has 35.5 nucleons.

Question

Quizplus · Accepted Answer

The reason for the molecular mass for chlorine not being an integer multiple of the molecular mass of hydrogen is due to the presence of different isotopes of chlorine. Chlorine has two stable isotopes - chlorine-35 and chlorine-37, with abundances of 75.78% and 24.22%, respectively. This leads to an average atomic mass of approximately 35.5, which is not an integer multiple of the atomic mass of hydrogen.
