You may want to reference (Page) section 5.6 while completing this problem. A gas mixture with a total pressure of 770 mmHg contains each of the following gases at the indicated partial pressures: 126 mmHg CO2, 234 mmHg Ar, and 193 mmHg O2. The mixture also contains helium gas. Part A What is the partial pressure of the helium gas? Express your answer in millimeters of mercury. PHe = 217 mmHg Submit Previous Answers Part B Correct Dalton's law of partial pressures states that the total pressure exerted by all of the gases in a mixture is the sum of the partial pressures exerted by the individual gases. The partial pressure of helium is determined by subtracting the partial pressures of CO2, Ar, and O2 from the total pressure. What mass of helium gas is present in a 10.2-L sample of this mixture at 278 K ? Express your answer in grams. - ΑΣΦ m = 5.14 ? g 09
