The Molar Volume of a Gas

Figure from experiment 5 from Advanced Chemistry with Vernier

Introduction

In this experiment, you will determine the molar volume of a gas by conducting a chemical reaction that produces a gas, as shown in the reaction equation below.

{\text{Mg}}\left( {\text{s}} \right){\text{ }} + {\text{ 2HCl}}\left( {{\text{aq}}} \right) \to {\text{MgC}}{{\text{l}}_{\text{2}}}\left( {{\text{aq}}} \right){\text{ }} + {\text{ }}{{\text{H}}_{\text{2}}}\left( {\text{g}} \right)

You will react a known mass of solid magnesium with an excess of hydrochloric acid, in a sealed vessel, and use the pressure change to calculate molar volume at STP.

Objectives

In this experiment, you will

  • Measure the gas production of a chemical reaction by a pressure change.
  • Determine the molar volume of the gas produced in the reaction.
  • Calculate the molar volume of a gas at STP.
