Unformatted text preview: were pumped into a tank with a volume of 5.0 L. Calculate the partial pressure of each gas and the total pressure in the tank at 25°C. Solution Where are we going? • To determine the partial pressure of each gas • To determine the total pressure in the tank at 25°C What do we know? He O 2 Tank p 1.00 atm 1.00 atm ? atm V 46 L 12 L 5.0 L I T 25°C + 273 = 298 K 25°C + 273 = 298 K 25°C + 273 = 298 K What information do we need? ,/ Ideal gas law PV = nRT ,/ R = 0.08206 L . atmlK . mol How do we get there? How many moles are present for each gas? PV n = RT nRT P=V (1.9 mcl:)(0.08206 1; . atrn/K . mcl:)(298 K) • PH = = 9.3 atm e 5.01; (0.49 mcl:)(0.08206 1; . atm/K . mcl:)(298 K) • Po = = 2.4 atm 2 5.01;...
