Chapter 21, Problem 21.27P

Interpretation Introduction

Interpretation:

Relative intensities of peaks with $\text{m/z}$ values as 34, 35 and 36 have to be predicted for ${\text{H}}_2\text{S}$.

Concept Introduction:

Nominal mass may be defined as mass of most abundant isotope of a particular ion or molecule. For instance carbon exist as two isotopes $\text{C-}12$ and $\text{C-}13$. $\text{C-}12$ is abundant as much as $98.9\text{ \%}$ while abundance of $\text{C-}13$ is only $\text{1}\text{.1 \%}$. So clearly nominal mass of carbon is $12\text{ g}$.
