1. Part A

A 3.00-L flask is filled with gaseous ammonia, NH3. The gas pressure measured at 24.0 ∘C is 1.75 atm . Assuming ideal gas behavior, how many grams of ammonia are in the flask?

Express your answer to three significant figures and include the appropriate units.

2. Part B

If 1.00 mol of argon is placed in a 0.500-L container at 30.0 ∘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)/mol2 and b=0.03219L/mol.

Express your answer to two significant figures and include the appropriate units.
