a. A 3.00-LL flask is filled with gaseous ammonia, NH3NH3. The gas pressure measured at 23.0 ∘C is 2.45 atm . Assuming ideal gas behavior, how many grams of ammonia are in the flask?   b. If 1.00 mol of argon is placed in a 0.500-L container at 23.0 ∘C , what is the difference between the ideal pressure (as predicted by the ideal gas law) and the real pressure (as predicted by the van der Waals equation)? For argon, a=1.345(L2⋅atm)/mol2a=1.345(L2⋅atm)/mol2 and b=0.03219L/molb=0.03219L/mol. Express your answer to two significant figures and include the appropriate units.

For many purposes we can treat propane (C3H8) as an ideal gas at temperatures above its boiling point of -42. °C. Suppose the temperature of a sample of propane gas is lowered from 13.0 °C to -17.0 °C, and at the same time the pressure is changed. If the initial pressure was 3.3 atm and the volume increased by 30.0%, what is the final pressure? Round your answer to 2 significant digits. a atm ☐ x10 X

Consider the apparatus shown in the figure. The container on the left is 22.4 L in volume and contains 1.0 atm of N₂ at 273 K. The container on the right is 33.6 L and contains 2.0 atm of O2, also at 273 K. The valve between the two containers is opened and the gases are allowed to mix. 22.4 L 1.0 atm 273 K 33.6 L 2.0 atm 273 K What is the mole fraction of N₂ in the resulting mixture? 0.75 0.25 0.40 0.60 0.50
