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?

From data gathered by Voyager 1, scientists have estimated the composition of the atmosphere of Titan, Saturn’s largest moon. The pressure on the surface of Titan is 1220 torr. The atmosphere consists of 82 mol % N2, 12 mol % Ar, and 6.0 mol % CH4. Calculate the partial pressure of each gas.

Step-by-Step Solution:
Step 1 of 3

Pressure & Wind: Forces on the Atmosphere  Newton’s First Law of Motion o “A force is required to make something move”  Pressure- force exerted per unit area due to the weight of the air (units of pressure = millibars mb) o Ex: more water in tank A = more pressure than tank B which has less water  If both tanks were connected the...
