Chapter 2, Problem 22E

Interpretation Introduction

Interpretation:

The approximate value mass-to-charge ratio (m/e) in grams per coulomb for the ions $\text{I}{}^{-}\text{and }\text{S}{}^{2-}$ should be determined. The reason of being approximate value should be explained.

Concept introduction:

The mass to charge ratio can be mathematically represented as follows:

$\text{mass-to-charge ratio}(m/e)\text{=}\frac{\text{Mass of the ion}}{\text{Charge of the ion}}$

For an atom, the mass number is the sum of number of protons and neutrons present in the nucleus. The charge is the number of electrons lost and accepted by an atom. If an electron is lost, atom will get +1 charge and if an electron is accepted, it will get -1 charge.
