NaCl concentrations in each bathing solution as measured by freezing point osmometer

M1 (2 M)	M2 (0.6 M)	M3 (0.15 M)	M4 (0.03 M)	M5 (0.006 M)	M6 (0.001 M)
1.836 ± 0.013	0.543 ± 0.005	0.138 ± 0.0005	0.027 ± 0.0003	0.004 ± 0.0003	0.001 ± 0.0

Values are reported in units of M; nominal values for each measurement are displayed in the top row. The measured values were calculated from the osmolarity by assuming only NaCl was present. No standard deviation was associated with M₆, as the measurements were at the limit of the device resolution (1 mOsm).
