Summary Introduction

To determine:

The normal level of urea nitrogen in adults in $\text{ppm}$.

Introduction:

Parts per million is used for determining the concentration of very dilute solutions. It is defined as the mass of solute in $\text{mg}$ that is present in $1.0\text{L}$ of solution. It is mathematically expressed as,

$\text{ppm}=\frac{\text{Mass}\text{of}\text{solute}\text{in}\text{mg}}{\text{Volume}\text{of}\text{solution}\text{in}\text{L}}$ (1)
