Alright so I need assistance with problem 6. The correct answer is C, I just need a justification on how to find the answer

freezing point of a O pression constant for benzene is 5.12 °c/m. The freezing point for benzene is 5.5 °C at 1.00 atmosphere pressure. A T --KF . m dT=-S-12. 0.15 c. 0.77 °C m.15m d 4.73 °C KS.12 e. 6.30 °C 4.732 6 Which molecule would have an ideal Van't Hoff factor of 2, assuming the complete dissociation? a. CO2 b. CaClz d. Na3P04 e. VF4 Carbonated beverages have a small volume of gas above the beverage, with a pressure of 3.75 atm. What is the solubility of the gas in the beverage if the Henry's Law constant is 3.4 102 mole per (L atm)? 7. 375 x34.10 a 0.13 M b. 3.62 M c. 3.75 M d. 3.79 M e. 7.84M

Explanation / Answer

6)

a)

CO2 will not dissociate in water since it is not ionic compound

b)

CaCl2 dissociates into 1 Ca2+ and 2 Cl-

So, i = 3

c)

KClO4 dissociates into 1 K+ and 2 ClO4-

So, i = 2

d)

Na3PO4 dissociates into 3 Na+ and 1 PO43-

So, i = 4

e)

VF4 dissociates into 1 V4+ and 1 F-

So, i = 5

So, c is the answer
