Chapter 6, Problem 6.98SP

Interpretation Introduction

Interpretation:

From the given molecular formulas, the correct formula for Decabrom compound has to be verified.

Concept introduction:

Molecular formula:

Molecular formula is same or multiple of empirical formula of the compound. Molecular formula lets us know the number of specific atoms present in the compound.

Number of moles = $\frac{\text{amount}\text{of}\text{mass}\text{of}\text{the}\text{element}}{\text{molar}\text{mass}\text{of}\text{the}\text{element}}$

Mass percentage of the element = $\frac{\text{mass}\text{of}\text{the}\text{element}}{\text{sample}\text{mass}}\text{×}\text{100}$
