please answer thank youHomework Answers
a)
C6H12O6 is a non electrolyte.
So, it will not dissociate
Hence Van’t Hoff factor would be 1
Answer: 1
b)
Calcium phosphate is Ca3(PO4)2
It dissociate into 3 Ca2+ ion and 2 PO43- ions.
So, there are total of 5 particles.
Hence Van’t Hoff factor would be 5
Answer: 5
c)
Ammonium carbonate is (NH4)2CO3
It dissociate into 2 NH4+ ion and 1 CO32- ions.
So, there are total of 3 particles.
Hence Van’t Hoff factor would be 3
Answer: 3

For an aqueous solution of HF, determine the van't Hoff factor assuming 0% ionization. For the same solution, determine the van't Hoff factor assuming 100% ionization. A solution is made by dissolving 0.0300 mol HF in 1.00 kg of water. The solution was found to freeze at -0.0644°C. Calculate the value of i and estimate the percent ionization of HF in this solution.
