CHAPTER 5: STUDY GUIDE
What is the standard unit for pressure?
1 atm = _____ mm Hg = ______ torr = ______ Pa = ______ in Hg = ______ lb/in
2
(psi)
What is Boyle's law?
What is Charles's law?
What is Avogadro's law?
What is the ideal gas law?
What is the value of the universal gas constant?
A sample of He gas has a volume of 5.73 L at a temperature of 36
o
C and a pressure of
2.31 atm.
Calculate the moles of He molecules present in this gas sample.
What will the
mass of this gas sample be?
What does STP stand for and what are its values?
What is the molar volume of an ideal gas at STP?
A sample of methane gas having a volume of 2.80 L at 25
o
C and 1.65 atm was mixed
with a sample of oxygen gas having a volume of 35.0 L at 31
o
C and 1.25 atm.
The
mixture was then ignited to form carbon dioxide and water.
Calculate the volume of CO
2
formed at a pressure of 2.50 atm and a temperature of 125
o
C.
(There are two ways to
solve this problem, can you do them both?)
How are the molar mass and the density of a gas related to each other?
