Options

A. `i=("normal malar mass")/("abnormal molar mass")`
B. `i=("abnormal molar mass")/("normal molar mass")`
C. `i=("observed colligative property ")/("calculated colligative property ")`
D. `i=("calculated colligative property ")/("observed colligative property")`

Answer

A, C

Explanation

van't Hoff factor (i) is a measure of association or dissociation of solute particles which can be calculated as
`i=("normal molar mass")/("abnormal molar mass")`
`=("observed colligative property ")/("calculated colligative property ")`
