Table for Question AP Chemistry 3.4 A Explain the Relationship Between the Macroscopic Properties of a Sample of Gas or Mixture of Gases Using the Questions question 1 — AP Chemistry

The mixture is heated to 198°C in a sealed, rigid 12.5 L container, at which point both substances are gases and the total pressure in the container is 2.30 atm. Calculate the number of moles of gas particles in the container.

D	For the correct calculated value: \[ \begin{aligned}	P V=n R T
	n=\frac{P V}{R T}=\frac{(2.30 ~atm)(12.5 ~L)}{\left(0.08206 \frac{~L \cdot ~atm}{~K \cdot ~mol}\right)(471 ~K)}=0.744 ~mol \end{aligned} \]	Point 04
