Chapter 14, Problem 14.111P

Interpretation Introduction

Interpretation:

Mass of semiconductor that produced from $\text{32}\text{.5 g}$ of molten gallium with $\text{20}\text{.4 L}$ white phosphorus vapour, after the loss of $\text{7}\text{.2\% }$ by purification has to be calculated.

Concept Introduction:

Mole:

Mole of substance that present in taken mole of sample is calculated by mass of substance is divided by molar mass of the substance.

    $\text{Mole}\text{=}\frac{\text{Mass}}{\text{Molar}\text{mass}}$

Ideal gas equation:

 It is a hypothetical law, which expresses relationship between temperature, volume, pressure and number of moles of gas.

    $\begin{array}{l}\text{PV}\text{=}\text{nRT}\\ \text{Where,}\\ \text{P-Pressure}\\ \text{V-Volume}\\ \text{R-Gas}\text{constant}\\ \text{T-Temperature}\\ \text{n-Number of moles}\end{array}$
