Interpretation:
The pressure of the gas have to be calculated.
Concept Introduction:
The
The ideal gas law consists of all the variables of a gas such as pressure (P), volume (V), number of moles (n) and temperature (T).

Answer to Problem 2STP
The pressure of the gas is-
C. 15.4 atm.
Explanation of Solution
Data given: Number of moles of the gas = 1.80 mole
Volume = 2.92 L
Temperature = 32 °C = (273 + 32) K = 305 K
R = 0.082 L atm/mol K
Reasons for incorrect options:
From the calculation we got the pressure of the gas is 15.4 atm.
So the answer is option C.
That means other options that is,
A. 1.62 atm
B. 8.57 atm
D. 22.4 atm are found to be incorrect.

- For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. ?
