Question: 1 a 095 m aqueous solution of an ionic compound...

Question details

1. A 0.95  m aqueous solution of an ionic compound with the formula MX has a freezing point of -2.9  ∘C .
Calculate the van't Hoff factor (i) for MX at this concentration. I got 1.7 but it said that was wrong

2. An aqueous KNO3 solution is made using 80.9 gof KNO3 diluted to a total solution volume of 2.00 L . (Assume a density of 1.05 g/mL for the solution.) Calculate the molality of the solution. I got .42 but it was marked wrong

answer both please
