Chapter 2, Problem 79E

Interpretation Introduction

Interpretation:

The composition (by mass) of the given alloy of gold and palladium is to be calculated from the given information.

Concept introduction: The total mass of an alloy made up of two elements is calculated by the formula,

$\text{Mass}=\left(\begin{array}{l}\text{Number}\text{of}\text{moles}\text{of}\text{first}\text{element}\times \text{Molar}\text{mass}\text{of}\text{first}\text{element}+\\ \text{Number}\text{of}\text{moles}\text{of}\text{second}\text{element}\times \text{Molar}\text{mass}\text{of}\text{second}\text{element}\end{array}\right)$

To determine: The composition (by mass) of the given alloy of gold and palladium.
