Chapter 5.1, Problem 5.8PP

Interpretation Introduction

Interpretation:

Volume of the nitrogen gas that has mass of $\text{10}\text{.0 g}$ has to be calculated that is present at $\text{30}°\text{C}$ and pressure of $\text{750}\text{torr}$.

Concept Introduction:

Ideal gas law is the one that relates Boyle’s law, Charles’s law and Avogadro’s law into one.  This can be expressed as,

    $PV=nRT$

Where,

    $P$ is the pressure.

    $V$ is the volume.

    $R$ is the ideal gas constant that has value of $\text{0}\text{.0821 L}\cdot \text{atm}\cdot {\text{K}}^{-1}\cdot {\text{mol}}^{-1}$.

    $T$ is the temperature in Kelvin.

    $n$ is the number of moles of gas.

Units of pressure can be converted into other units by using the conversion factor.  It is known that $\text{1}\text{atm}$ of pressure is equal to $\text{760 torr}$.  Conversion factors can be given as,

    $\frac{\text{1 atm}}{\text{760}\text{torr}}\text{or}\frac{\text{760 torr}}{\text{1 atm}}$
