# The Molar Volume of a Gas

Extracts from this document...

Introduction

LAB REPORT - THE MOLAR VOLUME OF A GAS Aim: To try the Avagadro's hypothesis of molar volume of a gas under STP. Introduction: Avagadro stated that the volume of one mole of any gas is 22.4 dm3 under STP. In the experiment, we measured the molar volume of H2. The formula for it is: Mg(s) + 2HCl (l) --> MgCl2 (aq) + H2 (g) A certain mass of magnesium ribbon is used to react with HCl and the volume of the H2 gas produced is measured. Then the conditions of the lab is measured and we calculated the value at standart temperature and pressure. Raw Data: Lenght of the whole Magnesium Ribbon: 64 cm. Mass of the whole Magnesum Ribbon: 0.81 g. ...read more.

Trial1: (2.2 x 0.81) / 64 = 0.02784375 / 24.31 = 0.001145 mol Mg (101497.4 x 0.0291) / (295 x 0.001145) = (101000 x V) / 273 8744.206469 = (101000 x V) / 273 V = 23.6 dm3 (23.6 - 22.4) / 22.4 = 0.0536 x 100 = % 5.36 Trial 2: (2.2 x 0.81) / 64 = 0.02784375 / 24.31 = 0.001145 mol Mg (101497.4 x 0.0294) / (295 x 0.001145) = (101000 x V) / 273 8834.352927 = (101000 x V) / 273 V = 23.9 dm3 (23.9 - 22.4) / 22.4 = 0.067 x 100 = % 6.7 Trial 3: (2.6 x 0.81) / 64 = 0.03290625 / 24.31 = 0.001354 mol Mg (101497.4 x 0.0339) / (295 x 0.001354) = (101000 x V) ...read more.

Conclusion

(% 4.02). The average result of 3 trials is 23.6 dm3 and the percent error for the average value is % 5.36. Evaluation: One source of error is, the aqueous solution of MgCl2 was mixed up with water so it could effect the vapor pressure. Also when equalizing the levels of both liquid in the big beaker the level of MgCl2 couldn't be seen precisely. Also there was air inside of the gas measuring tube because of the hole in the rubber stopper. To achieve better results, the hole on the rubber stopper could be filled with water. The water inside of the big beaker could be changed after every trial to at least lessen the amount of MgCl2 solution in the water. The level of the water can be seen more precisely if the gas measuring tube has different color measuring lines to increase the readability. ?? ?? ?? ?? Mert Mih�i ...read more.
