Evaluation of Gas Law Constant. Objective: To experimentally determine the value of the universal gas constant , R. Theory / Background : The ideal gas law equation is expressed as PV=nRT and is used in most problems dealing with changes situations involving gases. This law can be used to approximate the behaviour of various gases under many situations with a few limitations. The term PV = nRT is also called the compression factor and is a measure of the ideality of the gas. An ideal gas will always

behavior characteristics because it does not exactly follow the ideal gas law. In the ideal gas law, gas molecules are considered to have negligible volume and negligible intermolecular interactions (Averill and Eldredge, 2006). The ideal gas equation of state is not sufficient to describe the pressure, volume and temperature behavior of most real gases but real gases shows significant deviations from the behavior of an ideal gas. For real gases or non-ideal gases, the most common equation of states

CHM 1101 Introductory Chemistry Dawn Fox Medeba Uzzi August, 2007 Compiled and edited by Medeba Uzzi Authors’ Note This document is an initiative by the authors in an attempt to deal with what they think may be one of the reasons contributing to the relatively high failure rate in the introductory Chemistry course (CHM 1101) at the University of Guyana. It was brought to our attention that many first year students taking CHM 1101 are unable to efficiently cope with the frenetic pace

The ideal gas law is where the product of the pressure and the volume of one gram molecule of an ideal gas is equal to the product of the absolute temperature of the gas and the universal gas constant. This is represented by PV = nRT, where R is the ideal gas constant of 0.08206 L*atm/mol*k and is a relationship of energy to quantity of matter at any given temperature. An ideal gas has no definite volume or mass, unlike real gas. Pressure is also higher in ideal gas compared to real gas. Dalton's
