Question

A flask at room temperature contains exactly equal amounts (in
moles) of nitrogen and xenon.
a. Which of the two gases exerts the greater partial pressure?

Accepted Answer

Hey everyone. So here we have equal amounts of hydrogen gas and helium gas placing a flask at room temperature or ask which of the two gasses has the greater pressure pressure. So if you look at the ideal gas law, we have P P N. R. T. And here our temperature is constant. And so is our volume. The greater the number of moles, the greater the pressure and the number of malls is equal to mass bob Mueller mass. So for one g sample, so from moles of hydrogen at one graham, if I buy them all a mass in the Mueller mass of hydrogen, it's two because there's two hydrogen That was a mass hydrogen which is 1. grams. This will give us 2.016 g. So this will give us 0.5 moles. And from malls of helium that one g. What about the molar mass of helium? Which is 4.003g. And this gives us 0.25 balls. So hydrogen gas as the greater number of moles. So this is going to have the greater partial pressure. So the answer's gonna be hydrogen gas. Thanks for watching my video and I hope it was helpful
