1 ) sodium nitrate dissociates in two molecules, 0.8 M solution in 1 liter of water.

calcium acetate 3 molecule dissociation 3.6 M

0.8 moles ethylene glycol = 0,8 M solution

1 mole ethanol = 1 M solution

1.6 Moles calcium phosphate= 3.2 M solution

Order of freezing point depression from lowest to highest   C , A, D, E, B

2) ion formula FeBr3---> Fe (+3) + 3Br (-)
