Constructed Response . Topic 1: Matter and Energy




Set F. Diagram interpretation, molar volume, Avogadro’s law, Gas law calculation

Base your answer to questions 23 through 25 on the information and diagrams below.

Cylinder A contains 22.0 grams of CO2(g) and Cylinder B contains N2(g). The volumes,
pressures, and temperatures of the two gases are indicated under each cylinder.

A B


CO2(g) N2(g)

V = 12.3 L V = 12.3 L

23. How does the number molecules of CO2(g) in cylinder A 23.

compares to the number of molecules of N2(g) in

container B.

Your answer must include both CO2(g) and N2(g).



24. The temperature of CO2(g) is increased to 450. K and 24.

the volume of cylinder A remains constant. Show a

correct numerical setup for calculating the new pressure

of CO2(g) in cylinder A.
