MOLAR MASS OF BUTANE Name: Ingrid Foss Ballo Class: 2IBJ Team: Ingrid Foss Ballo and Maike Jule Sonnewald Petersen Date: Tuesday 30th of January, 2004 AIMS The purpose of this activity is to determine the molar mass of butane using gas from a butane lighter. The experiment depends on the fact that the molar volume of an ideal gas is 22,4L at standard temperature and pressure (0 ?C and 101,3 kPa). By measuring the volume occupied by a known mass of butane, and knowing that its molar volume is 22,4L at S.T.P., it is possible to calculate the molar mass of butane. METHODS AND TOOLS Equipment - Piece of glass tubing - approximately 24 cm long and with a diameter of approximately 25 mm, closed at one end (with markings for mL). - Container for water - Butane lighter - Restort stand, boss head and clamp - Thermometer (-10-100 ?C) Procedure We filled both the glass tubing and the container with water....
