WebYou are given two solutes: Aluminum sulfate [Al2 (SO4) 3] and sucrose [C12H22O11 If the vapor pressure is lowered by 2.00 mm Hg at 25.0 o C for both solutions, what is the mass of each of the solutes? The vapor pressure of pure water at 25 °C is 23.8 mm Hg, so the vapor pressure of your solution is 2.00 mm Hg lower which equals 21.8 mm Hg. Web[total ions = 3 thus, i = 3] Hence, A l 2 ( S O 4 ) 3 will exhibit largest freezing point depression due to the highest value of i . Video Explanation
