When 48.7g of benzamide C7H7NO are dissolved in 1300.g of a certain mystery liquid X, the freezing point of the solution is 2.3°C lower than the freezing point of pure X. On the other hand, when 48.7g of sodium chloride are dissolved in the same mass of X, the freezing point of the solution is 8.7°C lower than the freezing point of pure X.Calculate the van't Hoff factor for sodium chloride inX. Be sure your answer has a unit symbol, if necessary, and round your answer to 2 significant digits. Please dont round untill the end

When 58.6 g of alanine (C3H7NO₂) are dissolved in 1950. g of a certain mystery liquid X, the freezing point of the solution is 3.4 °C lower than the freezing point of pure X. On the other hand, when 58.6 g of iron (111) nitrate (Fe(NO3)3) are dissolved in the same mass of X, the freezing point of the solution is 4.5 °C lower than the freezing point of pure X. Calculate the van't Hoff factor for iron(III) nitrate in X. Be sure your answer has a unit symbol, if necessary, and is rounded to the correct number of significant digits. x10 X Ś

When 45.6 g of glycine C2H5NO2 are dissolved in 750. g of a certain mystery liquid X, the freezing point of the solution is 6.40°C less than the freezing point of pure X. Calculate the mass of iron(III) nitrate FeNO33 that must be dissolved in the same mass of X to produce the same depression in freezing point. The van't Hoff factor i=3.32 for iron(III) nitrate in X .Be sure your answer has a unit symbol, if necessary, and round your answer to 3 significant digits.

When 122. g of glycine (C₂H5NO₂) are dissolved in 1350. g of a certain mystery liquid X, the freezing point of the solution is 7.50 °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 i= 1.64 for sodium chloride in X. Be sure your answer has a unit symbol, if necessary, and round your answer to 3 significant digits. olo X 0.0 S
