Unformatted text preview: the lab room. According to perfect gas laws, all gases should react under the circumstances stated in Equation 1. Since we can account for Pressure, Volume, Temperature, and the ideal gas constant, we can solve for the number of particles in the gas and divide it by the weight of the gas which will tell us the molecular weight, thus allowing us to identify the unknown gas 1 .
