Question

when 219 grams of benzamide are dissolved in 800 grams of a certain mystery liquid x te freezing point of the solution is 7 degrees less than the freezing point of pure X. Calculate the van't Hoff factor for potassium bromide in X. Be sure your answer has a unit symbol, if necessary, and is rounded to the correct number of significant digits.

Answer 1

Step-by-step explanation:

• The formulae used in solving the problem ; ΔTf = i × Kf × m

• where ΔTf = depression in freezing point ,

• i = vant hoff factor 1 for non dissociable solutes ,
• Kf = freezing point constant for solvent

Appropriate substitution was done as shown in the attached file.
