PLEASE COMPLETE ASAP! PLEASE SHOW WORK FOR EACH TABLE CLEARLY AND IN CORRECT ORDER! I WILL GIVE YOU A GOOD RATING IF DONE CLEARLY AND CORRECTLY :) FEEL FREE TO MAKE YOUR OWN TABLE SINCE THIS ONE DOES NOT ALLOW YOU TO INPUT DATA.
UPDATE: Someone asked which solvent is being used. It does not specify in the data provided, it already gives the volume and the mass of the solvent so you would use that to find the density. All the data below is the data provided and the screenshots below.

When 81.4 g of alanine C3H7NO2 are dissolved in 650.g of a certain mystery liquid X, the freezing point of the solution is 8.90°C less than the freezing point of pure X. Calculate the mass of sodium chloride that must be dissolved in the same mass of X to produce the same depression in freezing point. The van't Hoff factor =i1.56 for sodium chloride in X.
