Partial pressure of
Concept Introduction:
Dolton’s law of partial pressure gives relation between total pressure of mixture of gases and partial pressure of distinct gases. The expression of relation can be given as follows:
Here,
A and B are individual gases.
Here,
Mole fraction is a relation between moles of constituent and total moles of all constituent in mixture. The expression of relation can be represented as follows:
Here,

Chemical Principles: The Quest for Insight
- In the discussion on the composition of air, mention is made of the fact that water vapor may have a concentration as high as 40,000 ppm. Calculate the partial pressure exerted by water vapor at this concentration. Assume that this represents a situation with 100% humidity. What temperature would be needed to achieve this value? (See Appendix G.)arrow_forwardGiven that a sample of air is made up of nitrogen, oxygen, and argon in the mole fractions 0.78 N2, 0.21 O2, and 0.010 Ar, what is the density of air at standard temperature and pressure?arrow_forward
