Chapter 22, Problem 22.69SP

Interpretation Introduction

Interpretation:

Kilograms of carbon needed is to be calculated.

Concept introduction:

The given problem can be solved by calculating number of moles using ideal gas equation and then calculating the mass.
Ideal gas equation is:
$\text{PV = nRT }$

where P is the pressure, $\text{V}$ is the volume, n is the number of moles and $\text{R}$ is the ideal gas constant and $\text{T}$ the temperature.


Given:

Pressure is $\text{740 mm}\text{Hg}$

$\text{740 mm}\text{Hg×}\frac{\text{1}\text{atm}}{\text{760}\text{mm}\text{Hg}}\text{= 0}\text{.974}\text{atm}$

Volume of hydrogen gas is $\text{1}{\text{.99×10}}^{\text{8}}\text{L}$

Temperature is ${\text{20}}^{\text{o}}\text{C}$
