Gas Stoichiometry - STLCC.edu

The volume-volume problems are the easiest since according to the Law of Coining Gas Volumes, gases coine at the same temperature and pressure in simple whole nuer of volumes. What this means is that we can use the coefficients in the balanced equation to form volume relationships just as we did in the earlier Stoichiometry problems when we used the coefficients to form mole relationships.

Partial Pressures - University of Sydney

Thus each gas in the mixture has the same volume but, depending on how many moles of each is present, exerts a different pressure, called its partial pressure. Dalton''s Law of Partial Pressures states that in a mixture of gases, the total pressure is the sum of the individual pressures of each gas present in the mixture - i.e. the sum of the partial pressures.
