Chapter 8, Problem 28QRT

Interpretation Introduction

Interpretation:

Pressure of water vapor has to be calculated at $150°C.$

Concept Introduction:

Ideal gas Equation:

Any gas is described by using four terms namely pressure, volume, temperature and the amount of gas. Thus combining three laws namely Boyle’s, Charles’s Law and Avogadro’s Hypothesis the following equation could be obtained. It is referred as ideal gas equation.

  $\begin{array}{l}\text{V }\propto \frac{\text{nT}}{\text{P}}\\ \text{V = R}\frac{\text{nT}}{\text{P}}\\ \text{PV = nRT}\end{array}$

Here,

  n = moles of gas

    P = Pressure

    T = Temperature

    R = gas constant

  $\text{n}\text{ =}\frac{\text{m}}{\text{M}}$

Here,

  $\text{n}$ = Number of moles.

  M = Molar mass

  m = mass.
