An unknown gas evolved from the fermentation of glucose is found to effuse through a porous barrier in 15.0 min. Under the same conditions of temperature and pressure, it takes an equal volume of N2 12.0 min to effuse through the same barrier. Calculate the molar mass of the unknown gas and suggest what the gas might be.
Week 3 Notes Tuesday, September 6, 201611:06 AM Important Points ○ LimitingReagent:Reactant used up first in the reaction ○ Theoretical Yield: Is the amount of productthat would result if all the limiting reagent reacted MAXIMUMobtainable result ○ Actual Yield is the amount of product actually obtained out of a reaction. • More on Titrations ○ Titrationcan be usedin the analysis of acid-baseand redox reactions • Physical Characteristicsof Gases ○ Gases assumethe volume and shapeof their containers ○ Most compressiblestate of matter ○ Gases will mix evenly and completelywhen confinedto the same container ○ Much lower densitiesthan liquidsand solids • Pressure ○ 1 pascal(Pa) = 1 N/m^2
