In ideal gas equation calculations, expressing pressure in Pascals (PA), necessitates the use of the gas constant, R, equal to . A) 0.08206 atm L mol^-¹K^-¹ B) 1.987 cal mol^-¹K^-¹ C) 8.314 J mol^-¹K^-¹ D) 62.36 L torr mol^-¹K^-¹ E) none of the above

Question

Quizplus · Accepted Answer

The ideal gas equation is PV=nRT where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is the temperature. The units of R depend on the units used for the other variables. If pressure is expressed in Pascals (Pa), volume in cubic meters (m3), and temperature in Kelvin (K), then R has the value 8.314 J mol-1 K-1.
