#1 - A balloon is filled with 3 gases: nitrogen, oxygen, and hydrogen. The total pressure of the gases is 8.51 atm. If the partial pressure of nitrogen is 3.84 atm, and the partial pressure of oxygen is 2.20 atm, calculate the partial pressure of hydrogen.
Partial pressure of
hydrogen = 2.47 atm
#2 - A sample of gas is 7.89 L at 293 K. How many degrees must the temperature decrease to change the volume to 6.00 L?
It will change from 293 K to 223 K,
which is a difference of 70 K.
#3 - A piston filled with oxygen gas has a pressure of 240.0 mm Hg at 225 mL. If the pressure is decreased to 0.150 atm, what will be the new volume of the gas?
Don’t forget to change P1 to atm!
#4 - A sample of gas at 150.0 K has a pressure of 900.0 mm Hg. It is cooled until the pressure reads 700.0 mm Hg.
What is the new temperature in both Kelvin and degrees Celsius?
0.00968 moles O2
#6 – 560.0 mL of nitrogen are measured at 28.0oC and 1.50 atm. Calculate the volume under STP.
#7 - Determine how many liters 8.80 g carbon dioxide gas would occupy at STP.
