Exam 5 Formula’s Under: Flash Cards 1 ATM is = to… 760 torr760 mm Hg101.25 K Pascal Ideal Gas Law p * v = p * v = n * r * t Is this information for COMBINED gas law or IDEAL gas law? p = ______ and should be in _____. v = ______ and should be in _____. n = ______. r = ______. t = ______ and should be in _____. d = ______. p = PRESSURE in ATM v = VOLUME in LITERS n = # OF MOLES r = GAS CONSTANT, 0.08206 t = TEMPERATURE in KELVIN d = DENSITY Ideal Gas LawMolar Mass = _______ / _______orMolar Mass = _______ /________ Molar mass = (mass x r x t) / (p x v) Molar mass = (d x r x t) / p Use the Combined Gas Law when you have _ ______. Use when you have 2 CONDITIONS! Combined Gas Law Formula (1) *For this formula you ____ ____ need to convert mL to Liters** (P1 x V1) / T1 = (P2 x V2) / T2 DO NOT CONVERT ML TO L!
