The correct answer to this item is (A). This question requires knowledge about the fundamental equations of
ideal gases. Using the equation PV = nRT, one can solve for V: V = nRT/P. By looking up the value for the gas
constant, R, one can plug in values for temperature, pressure, and moles to determine the volume of the gas.
Relationship Analysis Questions
This type of question consists of two statements. The first makes an assertion of fact, while the second
proposes an explanation for it. The tricky thing about this type of question is that either or even both
statements may be FALSE!
Your answers to this type of question must be entered on a special section (labeled “Chemistry”) in
the lower left-hand corner of page 2 of your answer sheet. The oval spaces for these questions are num-
bered beginning with 101 and must be coded according to the following directions:
 
Directions: Each question on page 370 consists of two statements. Each statement in the left-hand
column is referred to as I, and each statement in the right-hand column as II. For each question,
determine whether I is true or false and whether II is true or false and fill in the corresponding T and
F oval spaces on your answer sheet. If, but only if, statement II is a correct explanation of statement
I, darken the oval space labeled CE.
