A moving boundary experiment was performed at 25°C with 0.100 M KCI on the bottom and (initially) 0.0700 M NaCl on top. The transport numbers of K+ and Na+ in these solutions are 0.490 and 0.388, respectively. The boundary moved downward. The cross-sectional area of the tube was 0.100 cm². The charge passed through was 96.5 coulombs. How far did the boundary move in cm?
