Chapter 4, Problem 4.37QP

Interpretation Introduction

Interpretation: The ratio of platinum to tin in a compound present in the solution, the mass of platinum complex and stannous chloride per $100\text{mL}$ of the solution, the path length and the molar absorptivity of the compound formed on the reaction is given. The absorbance of the solution is to be determined.

Concept introduction: The concentration of the solution is calculated by the formula,

$\text{Concentration}=\frac{\text{Milligrams}\text{of}\text{solute}}{\text{Molar}\text{mass}\times \text{Volume}\text{of}\text{the}\text{solution}\text{in}\text{milliliters}}$

The absorbance of the solution is given by the formula,

$\text{Absorbance}=\text{Molar}\text{absorptivity}\times \text{Path}\text{length}\times \text{Molar}\text{concentration}$

To determine: The absorbance of the solution.
