When 109.0 g of glycine C2H5NO2 are dissolved in 1050.0 g of a certain mystery liquid X, the freezing point of the solution is 6.1 °C lower than the freezing point of pure X. On the other hand, when 109.0 g of sodium chloride are dissolved in the same mass of X, the freezing point of the solution is 11.9 °C lower than the freezing point of pure X.
Calculate the van't Hoff factor for sodium chloride in X.

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
