I have the answers, I am just interested in the formulas so that I can solve the problems, thanks!

1. Find the boiling point of a solution composed of 110g of HgCl2 (a non-ionizing solute) in 175g of water.

2. Find the freezing point of a solution composed of 50g IBr in 120 g of water. Assume 100% ionization. KBr = k1+Br1-.

3. Find the freezing point of solution composed of 74.15g MG(NO3)2 in 90 g of water. Assume 100% ionization.

4. Calculate the freezing point of a solution containing 12.0g of sucrose (C12H22O11) in 120g of water.

5. Calculate the boiling point of a solution containing 42.00 g of CuSO4 in 300g of water. CuSO4=Cu2+ + SO42-.

6. Find the molecular mass of a non-ionizing solute if 72g dissolved in 300g of water raise the boiling point to 100.860 degrees Celsius.

7. Find the molecular mass of a non-ionizing solute if 87.85g dissolved in 500g of water lower the freezing point to -3.00 degrees Celsius.
