What is its mass % in an.Answer · 0 votesHello. In this problem, we are told in an experiment, the van Hoff factor for sodium sulfate was calculated to be 2.80 in aqueous sodium sulfate solution has the freezing point of minus 2.35 degrees Celsius. We are asked to find the mass percent of sodium sulfate in this solution. The first thing we're going to do then is find the morality. And we will then convert morality to mass percent to find morality. We're going to make use of the formula for the depression of freezing point. For a solution which is given by the change in the freezing point is equal to the Van Hoff factor times a freezing point depression constant, times morality. We're told we have an aqueous sodium sulfate solution. So our Sullivan is water. Water has the freezing point depression constant at 1.86°C perm allow We were told that the calculated van Hoff factor was 2.80 and the change in the freezing point is equal to the freezing point for pure water minus the freezing point. For the solution, water has a freezi…MoreDoubtnutQuestionvan't Hoff factor of 0.1 molal CaCl2 solution will be (Assume CaCl2 dissociates completely in solution)A: 2B: 4C: 1D: 3Answer · 888 votesThe correct answer is: DMoreTopprQuestionCalculate the amount of CaCl2 (van't Hoff factor i = 2.47 ) dissolved in 2.5 L solution so that its osmotic pressure at 300K is 0.75 atmosphere.Given: Molar mass of CaCl2 is 111 g. mol^-1 , R = 0.082 L.atm.

In other words, it is a measure of the extent of dissociation of a solute in a solution.If 80% of calcium chloride (CaCl2) dissociates, it means that for every 100 molecules of CaCl2 added to the solution, 80 of them will dissociate into three ions: one Ca2+ ion and two Cl- ions.Therefore, the total number of particles in the solution will be greater than the number of formula units of CaCl2 added.The van 't Hoff factor for CaCl2 in this case can be calculated using the formula:i = (number of particles in solution) / (number of formula units of solute)Since each CaCl2 molecule dissociates into three particles, the number of particles in solution will be:(number of formula units of CaCl2) x (number of particles per formula unit) x (fraction dissociated)= 1…MoreBartleby.comQuestionThe osmotic pressure of a 0.010 M aqueous solution of CaCl2 is found to be 0.674 atm at 25 °C.
