Properties of Gases

ABSTRACT

The values for the universal gas constant R, and the volume of one mole of gas were determined. The experiment values of R and the volume of one mole of gas were then compared to the accepted values. The experimental values of R obtained were 0.09067 (L∙atm/mol∙K), 0.09514 (L∙atm/mol∙K), and 0.09040 (L∙atm/mol∙K). The molar volumes of hydrogen gas obtained were 0.1306 (L/mol), 0.1365 (L/mol), and 0.1390 (L/mol). The percent error of R was 12.20%, and the percent error of the molar volume was 99.40%.

INTRODUCTION

The purpose of this experiment was to determine the value of the universal gas constant R (L∙atm/mol∙K), and the molar volume of hydrogen gas. In this experiment, a known mass of magnesium reacted with an excess amount of hydrochloric acid to produce hydrogen gas. The reaction that took place in the experiment was as follows:

Mg (s) + 2HCl (aq) MgCl2 (aq) + H2 (g)

The balanced ...
