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.
a great book for spring and a lesson involving kites (writing about a time they flew a kite, writing how-to fly kites, explaining why they like to or do not like to fly a kite, kite fractions, kite symmetry, a lesson on wind)
