<Chapter 08 Problem 7 < 7 of 27 Review I Constants I Periodic Table Learning Goal: To use partial pressure in gas law calculations. A volume of 18.0 L contains a mixture of 0.250 mole N2 , 0.250 mole O2 , and an unknown quantity of He. The temperature of the mixture is 0 °C, and the total pressure is 1.00 atm How many grams of helium are present in the In a mixture of gases, the total pressure of the gas mixture is equal to the sum of the partial pressures of the individual gases. For example, if you have a mixture of helium at 2 atm and argon at 4 atm, then the total pressure of the gas inside the cylinder is 6 atm. (Figure mixture? gas Express your answer to three significant figures and include the appropriate units. View Available Hint(s) Figure Hint 1. Find the total number of moles 1 of 1 The following values are given: . P 1.00 atm V 18.0 L T 0 °C R 0.0821 L atm/(mole K) 3 nRT, determine the total number of moles of gas, Using the ideal gas law, PV ntotal in the container.
