WebIf the freezing point of the solution had been incorrectly read 0.3 degrees lower than the true freezing point, would the calculated molar mass of the solute have been too high or too low? The calculated molar mass of the solute would have been too low by increasing the magnitude of the delta T. WebAccording to Henry’s law, for an ideal solution the solubility, Cg, of a gas (1.38 × 10 −3 mol L −1, in this case) is directly proportional to the pressure, Pg, of the undissolved gas above the solution (101.3 kPa in this case). Because both Cg and Pg are known, this relation can be rearranged and used to solve for k . fbi raids mark houck
