Chapter 5, Problem 5.53P

Interpretation Introduction

Interpretation:The reason for 1 mol of Kr and 1 mol of He to have same volume at STP needs to be explained using the kinetic-molecular theory.

Concept Introduction:

The ideal gas equation can be used to calculate P, V, T and number of moles of gases. It is basically the combination of different gas laws such as Boyle’s law, Charles’s law, Gay-Lussac law and Avogadro law. The ideal gas equation can be written as:

  $\begin{array}{l}\text{P}\times \text{V = n}\times \text{R}\times \text{T}\\ \text{P = pressure }\\ \text{V = volume }\\ \text{n = number of moles }\\ \text{R = gas constant }\\ \text{T = temperature }\end{array}$
