Welcome back everyone what mass and grams of ethanol, ethyl alcohol C two H five oh H is required for an agreed solution that freezes at negative 5.50 Celsius. The amount of water solvent to be used for the solution is 750 g. The value of k. F, freezing point constant for water is 1.86 degrees Celsius times kilograms, divided by molds.
