Suppose a student performed a similar experiment with a different unknown. Given the data in the table, what is the van't Hoff factor of the unknown substance? i = Kr of water freezing point of pure water molality of solution freezing point of solution 1.86 °C/m 0.0 °C 0.255 mol/kg -1.90 °C Suppose a student performed a similar experiment with a different unknown.
