Notes 7-3: Dalton’s LawName____________________Partial PressureNotes: The pressure in a container is the sum of the pressures of its gasesPtotal= P1+ P2+ P3Application Problems: partial pressures, collecting gases and mol fractions1.A container holds three different gases. The partial pressures are; 25 kPa, 42 kPa, and 63 kPa. Find the total pressure.2.A tank holds two gases. The total pressure is 150. atm. If the partial pressure of one of the gases is 35 atm. Find the pressure of the other gas.3.A flask contains Ne at 542 mmHg together with Ar at 234 mmHg. What will the total pressure be?4.A tank is filled with oxygen and nitrogen. The total pressure of the tank is 6.45 atm, and the partial pressure of the nitrogen is 2.07 atm. What is the partial pressure of the oxygen? 5.If a container holds 5.00 moles of gas and the total pressure is 5.00 atm., what is the partial pressure for each mole of gas?
