Directions: Solve the following problems using GRESA and answer the last question.
1. Calculate the pressure exerted by a 0.25 mole sulfur hexafluoride in a steel vessel
having a capacity of 1 250 mL at 70.0 0C.
2. Fermentation of glucose produces gas in the form of carbon dioxide. How many moles
of carbon dioxide is produced if 0.78 L of carbon dioxide at 20.1 0C and 1.00 atm was
collected during the process?
3. How was the ideal gas equation derived? Explain.
1. n=0.25 mol
V=1250 mL = 1.25 L
T=70.0 + 273=343 K
Ideal Gas Law:
R = 0.08206 L×atm/mol×K
Answer: 5.63 atm
2. V=0.78 L
T=20.1 + 273 = 293.1 K
Answer: 0.032 mol
3. PV = nRT
P is the pressure of the ideal gas.
V is the volume of the ideal gas.
n is the amount of ideal gas measured in terms of moles.
R is the universal gas constant.
T is the temperature.
