A 1-L flask is filled with 1.40 g of argon at 25 °C. A sample of ethane vapour is added to the same flask until the total pressure is 1.46 bar. Part A What is the partial pressure of argon, Par, in the flask? Express your answer to three significant figures and include the appropriate units. ► View Available Hint(s) ША PAr = Value Units ?

What is the temperature in K of 0.500 mole of neon in a 2.00L vessel at 4.32 bar? R = 0.08314 L· bar/mol·K.

Consider the following situation:  You have a 50 L tank of compressed air at 15 atm and 100 ºC.  You then pass the compressed air through a "titanium getter" which contains fragments of hot titanium metal.  The purpose of the "getter" is to remove oxygen gas from the sample as Ti reacts with oxygen to form solid TiO2 (known as titania).  Once the purified air is passed through the getter is it cooled back down to  100 ºC and fills another 50 L storage tank.  If air typically contains about 20% oxygen, what could the pressure in the storage tank be?     Question 2 options:   A)  12 atm   B)  15 atm   C)  18 atm   D)  24 atm

Hot gaes Expanding A mixture hot gases expands, changing volume from 2.45 L to 6.82 L, against a constant pressure of 3.22 atm. The P-Vwork involved is Latm .
