Problem 1PE

Relating Mole Fractions and Partial Pressures

A study of the effects of certain gases on plant growth requires a synthetic atmosphere composed of 1.5 mol % CO2, 18.0 mol % O2, and 80.5 mol % Ar. (a) Calculate the partial pressure of O2 in the mixture if the total pressure of the atmosphere is to be 745 torr. (b) If this atmosphere is to be held in a 121-L space at 295 K, how many moles of O2 are needed?

A 4.0-L vessel containing N2 at STP and a 2.0-L vessel containing H2 at STP are connected by a valve. If the valve is opened allowing the two gases to mix, what is the mole fraction of hydrogen in the mixture? (a) 0.034, (b) 0.33, (c) 0.50, (d) 0.67,

(e) 0.96.
