Part A
A 3.00-L flask is filled with gaseous ammonia, NH3. The gaspressure measured at 25.0 ∘C is 2.05 atm . Assuming ideal gasbehavior, how many grams of ammonia are in the flask?
Express your answer to three significant figures and include theappropriate units.
Part B
If 1.00 mol of argon is placed in a 0.500-L container at 28.0 ∘C, what is the difference between the ideal pressure (as predictedby the ideal gas law) and the real pressure (as predicted by thevan der Waals equation)?
For argon, a=1.345(L2â‹…atm)/mol2 andb=0.03219L/mol.
Express your answer to two significant figures and include theappropriate units.
