Chapter 5:

1. Which of the following is not a

measurement of pressure?

a. mm Hg b. torr c. atmosphere d. manometers

2. If the volume of a gas

increases when the temperature

and moles of gas are held constant,

what will happen to the gas

pressure?

a. The pressure will also remain constant.

b. The pressure will increase.

c. The pressure will decrease.

d. The pressure change depends on the chemical composition of the gas.

4. If two ideal gases, A and B, are

mixed together, what will be the

final pressure of the mixture?

a. the total pressure will be the difference between the partial pressure of A and the partial pressure of B b. the total pressure will be the sum of the partial pressures of A and B c. the total pressure will depend on the chemical identities of A and B d. the total pressure will be equal to whichever gas has the greater partial pressure

5. Which of the following

equations correctly represents a

method for determining the molar

mass of an unknown gas using the

ideal gas law?

a. M = PV/gRT b. M = PV/RT c. M = gRT/PV d. M = nRT/PV
