Which Box Has the Highest Pressure and Density?

Click For Summary
SUMMARY

The discussion focuses on determining the total pressure, partial pressure of nitrogen, and density in three identical boxes containing different mixtures of O2 and N2. The conclusions drawn are that total pressure ranks as 2 < 1 < 3, partial pressure of nitrogen ranks as 2 < 3 < 1, and density ranks as 2 < 1 < 3. The calculations are based on the ideal gas law and the concept of mole fractions, confirming the accuracy of the initial assessments made by the participant.

PREREQUISITES
  • Understanding of the ideal gas law
  • Knowledge of mole fractions
  • Familiarity with concepts of partial pressure
  • Basic principles of density calculation
NEXT STEPS
  • Study the ideal gas law in detail
  • Learn about mole fraction calculations
  • Explore the concept of partial pressures in gas mixtures
  • Investigate density calculations for gas mixtures
USEFUL FOR

Students studying chemistry, educators teaching gas laws, and anyone interested in understanding gas behavior in mixtures.

How to count molecules and determine density, partial pressure and total pressure?

Homework Statement



Consider three identical boxes each containing a different mixture of O2 and N2. In box #1 are 3 molecules of O2 and 7 molecules of N2. In box #2 are 1 molecule of O2 and 2 molecules of N2. In box #3 are 10 molecules of O2 and 3 molecules of N2. If temperature and volume for all three samples are the same, rank them (use "less than," "greater than," or equal symbols; 1< 2 < 3 or 2 > 1 = 3 with respect to:

a) total pressure

b)partial pressure of nitrogen

c)density


Homework Equations



My attempt is according to counting the number of molecules is

a) total pressure is 2 < 1 < 3

b) partial pressure is 2 < 3 < 1

c)density is 2 < 1 < 3

I want to just make sure and compare with someone if I am correct and if not please explain how to determine this thank you.
