This law brings Boyle's, Charle's, Avogadro's, and Gay-Lussac's laws together in one neat, easy to use package: PV = nRT. Using simple algebra any of this variables can be isolated: P = nRT/V, V = nRT/P, T = PV/nR, n = PV/RT, or the ideal gas constant R computed. All gas calculations must be made using temperatures in Kelvin. If the ideal gas constant R = 0.08206 L∙atm/mol∙K, what volume will 1.00 mol of a gas occupy at 1.00 atm of pressure and 273 K?
