Results of DeltaT and i stated 2nd paragraph: sources of errors discussed The objective is The colligative properties are the properties that undergo a change when a solute is introduced to a solvent. Freezing point depression is also a colligative property. The addition of a solute to a solvent reduces the freezing point of the resulting solution. The freezing point of the solution is always lower than the freezing point of the solvent. This difference in the freezing point between solvent and solution is called freezing point depression. The freezing point depression is directly proportional to the molality of the solution or the number of moles of solute present in the solution.Gypsum (CaSO4) is one of common precipitants in brackish water desalination processes.

- You work with two amino acids. Tryptophan (MW=204 Da) and Methionine (MW=149 Da). You make varioussolutions of each amino acid separately and compare them When you compare two solutions at the same percentage concentration (e.g. 1%), there are moremoles of Tryptophan in solution than moles of Methionine because the molecular weight of Tryptophan ishigher. When you compare two 1-liter solutions containing these amino acids at a 10mM concentration, thereis the same number of amino acid molecules in each solution-The density of aluminum is 2.70 g/cm'.
