mass-average velocity

in electrolytes
Also contains definition of: molar average velocity in electrolytes
https://doi.org/10.1351/goldbook.M03711
Mass-average velocity: νb=ρ1 CiMiνi Cf. molar average velocity: νm=ct1 ciνi with ct=ci where Mi = molar mass, ct = total concentration (molm1),ρ = density of the solution (kgm3).
