An anion has an electrophoretic mobility of -2.50 cm2 /kV - min on a CE system containing a 30 cm long capillary with a detector located 25.0 cm from the point of injection. If the electroosmotic mobility of the buffer is 4.10 cm- /kV - min, and the applied voltage is 15.0 kV, what are the migration time (v) and the apparent mobility (Ha)?
