Unformatted text preview: **R = Ideal Gas Constant **R = 0.08206 L atm / K mol **if using ideal gas constant, you must convert volume to litres, pressure to atm--An ideal gas is present in a cylinder of volume 5.0 x 10^2mL at 30.00*C with a pressure of 710Torr. The gas is compressed to Calculate the new pressure Sheet1 Page 2--Molar Mass and Density MM = dRT / PV Molar Mass / Empirical Formula = take closest whole number i.e. CH2---Gas stoichiometry Reactions involving gas evolution, mass, temperature, pressure, mol (ideal gas equation). Molar Volume The volume one mol of any idea gas will occupy at 0*C and 1atm pressure (STP). Molar volume = 22.42L---...
