I have a few questions that I have absolutely no clue on. Please help me! Lol

1. 97.5 G of sucrose, c12h22o11 are dissolved in 185 G of water. At what temperature will this solution boil? What temperature will it freeze?

2. I know these aren't boiling or freezing points but I need help on them too.
Calculate the molarity of 100.0mL of solution in which 48.4G of CaCl2 are dissolved.


3. Calculate the molality of a sugar water solution that freezes at -2.56 Degrees C.


Thanks for all help :)
