Just answer part 2 and 3 please
(0.3 point) Part 1 ii See Periodic TableSee Hint A solution is created by dissolving 12.5 grams of ammonium chloride in enough water to make 355 mL of solution. How many moles of ammonium chloride are present in the resulting solution? moles of NH4CI 0.233 When chemists work with solid materials, we simply weigh out amounts of solid reagents and calculate mole amounts when thinking about stoichiometry. However, when we dissolve a solid...

QUESTION 10
Information - Colligative
Properties
Colligative properties of solutions are those properties which
depend only on the number of dissolved solute particles in solution
not the chemical properties of the solute. For example when a
solute is dissolved in a solvent, vapor pressure

QUESTION 25 The molar mass of a compound can be determined by the freezing point depression method. The solution must be relatively dilute and you must know the molal freezing point depression constant of the solvent, Kf: Which statement regarding Kris true? Kf should be small so that the solvent will not sublimate, Kf will change depending on what solute is dissolved in the solvent. Kfshould be negative so the freezing point of the solution will decrease. Kfshould be large...

Colligative properties, such as boiling point elevation, depend on the number of dissolved particles in solution. For nonelectrolytes, no dissociation occurs, and so you can use the number of moles of solute to calculate both molality and molarity. In contrast, electrolytes dissociate, and therefore the molality and molarity must be calculated based on the number of moles of dissociated particles or ions. There are two ions per formula unit of NaCl. Therefore, we would expect the freezing-point depression ΔTf of...
