Chapter 3, Problem 127AP

Interpretation Introduction

Interpretation:

The empirical formulasfor the two compounds of platinum are to be determined with given percent by mass of chlorine.

Concept introduction:

Empirical formula is the formula having the simplest whole number ratios of various atoms present in a compound.

The number of moles of a reactant is calculated by the following formula:

$m=\frac{wt}{MW}$

Here, $m$ is the number of moles of a compound, $wt$ is the weight of the compound, and $MW$ is the molecular weight of the compound.

The mass of platinum is calculated as $m=\text{total}\text{mass}-\text{mass}\text{of chlorine}$.
