Mole Fraction (X): the fraction of the total number of moles in a mixture that each component contributes; multiplying X by 100 gives the mole percent; the sum of the mole fractions of all components in any mixture must be 1 or 100%; the total pressure is due to the total number of moles, so the partial pressure of gas A is the total pressure multiplied by the mole fraction of A, so P(A) = X(A) x P total
How to Calculate the Concentration of a Chemical Solution: Do the units for solution concentration confuse you? Get definitions and examples for calculating percent composition by mass, mole fraction, molarity, molality, and normality.
Ten Hours Since Obama Contained ISIS Ten hours ago, the Moron in Chief announced that he has contained the JV team He also believes that 0.0004 mole fraction of an harmless inert gas is the biggest threat Paris has ever faced.
Kinetic Molecular Theory applied to Dalton's law of partial pressures: adding a given amount of gas A to a given amount of gas B causes an increase in total number of molecules in proportion the amount of A added; this increases causes a corresponding increase in number of collisions per second & a corresponding increase in pressure; each gas exerts a fraction of total pressure based on the fraction of molecules (or moles) of that gas in the mixture
