Unformatted text preview: 3.3. IDEAL MIXTURES OF IDEAL GASES 79 One can find a convenient relation between species molar concentration and species mole fraction by the following operations ρ i = n i V n n , (3.49) = n i n n V , (3.50) = y i ρ. (3.51) A similar relation exists between species molar concentration and species mass fraction via ρ i = n i V m m M i M i , (3.52) = m V = m i bracehtipdownleft bracehtipuprightbracehtipupleft bracehtipdownright n i M i mM i , (3.53) = ρ = c i bracehtipdownleftbracehtipuprightbracehtipupleftbracehtipdownright m i m 1 M i , (3.54) = ρ c i M i . (3.55) The specific volumes, mass and molar, are similar. One takes v = V m , v = V n , (3.56) v i = V m i , v i = V n i . (3.57) Note that this definition of molar specific volume is not the partial molar volume defined in the chemical engineering literature, which takes the form v i = ∂V/∂n i | T,P,n j ,i negationslash = j ....
