In the video, a 5.0 L flask at 20°C was shown, containing 1.25 mol of He and 0.50 mol of H₂, at a total pressure of 8.4 atm. Which of the following outcomes would you expect of an additional 0.50 mol of H₂ were added to the flask? Select all that apply. the mole fraction of H₂ would double the partial pressure of He would remain the same the mole fraction of He would remain the same the total gas pressure would increase by 50% the total mass of gas would increase by about 1.0 g
