Consider a sample that has 121.6 g of K2SO4 dissolved in water to make a solution that is 1.31 L. When responding, please only input your numeric value with three significant figures. No units. 1). What is the molarity of the compound in this sample? 2). What is the molality of the compound in this sample? Density of the solution is 1.06 g/mL. 3). Based on the dissociation reaction for K2SO4, determine the Van’t Hoff Factor (i). 4). What is the freezing point of the solution if the Kf of water is 1.86°C/m and the freezing point is 0°Celsius. Assume complete dissociation. Hint: ΔTf = i(Kf m)
