What is the volume of 1 mole of an ideal gas at STP?
5.68. Which of the following are not characteristics of an ideal gas?
a. The molecules of gas have little volume compared with
the volume that they occupy.
b. Its volume is independent of temperature.
c. The density of all ideal gases is the same.
d. Gas atoms or molecules do not interact with one another.
*5.69. What does the slope represent in a graph of pressure as a
function of 1/V at constant temperature for an ideal gas?
