The figure above represent three sealed, rigid 1 L containers each containing a gas at 298 K. The pressure of the nitrogen gas is 4 atm. The ratio for the number of gas molecules is shown in the diagram. What is the total pressure at 298K after the gases are combined into a previously evacuated 2 L container? Assumer the gases will not react when combined.
(A) 3.5 atm
(B) 7 atm
(C) 14 atm
(D) 28 atm

Learning Intentions

• We will learn what variables affect properties of a gas.

• We will learn the ideal gas law equation, including what each letter in the equation stands for and the proper unit for each variable. 

• We will learn how to solve for any unknown variable using the ideal gas law equation.

• We will learn other equations related to gases.

• We will learn how to design an investigation to determine the molar mass of a volatile liquid.

Closing Task:

You can create a plan to determine the molar mass of an unknown volatile liquid. 

Content Standards being covered:

The gaseous state can be effectively modeled with a mathematical equation relating various macroscopic properties. A gas has neither a definite volume nor a definite shape, because the effects of attractive forces are minimal, we usually assume that the particles move independently. (E.K. 2.A.2)
