Chapter 4, Problem 31PS

Interpretation Introduction

Interpretation:

The empirical formula of styrene should be determined.

Concept introduction:

• Empirical formula of a compound represents the smallest whole number relative ratio of elements in that compound.
• Equation for finding Molecular formula from the empirical formula,

  $\frac{\text{Molar}\text{mass}}{\text{Empirical}\text{formula mass}}\times \text{ Empirical formula}$

• The molar mass of an element or compound is the mass in grams of 1 mole of that substance, and it is expressed in the unit of grams per mol (g/mol).
