A solution is prepaed by mixing 0.2235 moles of NaNO3 with 217.4 g of water. Its density is 1.133 g mL^-1. If Kf = 1.87 °C m^-1 and the solute is completely ionized, what is the expected freezing point of the solution? Report answer two places past the decimal point.
If a solute like a chlorobenzene (molar mass = 112.6 g/mol) were used by mistake instead of naphthalene for the determination of the freezing point constant, How would the calculated value of Kf compare to that expected from naphthalene (high, low, now effect)? Explain.
The normal freezing point of a certain liquid X is -6.20 °C, but when 7.45 g of benzamide (C,H,NO) are dissolved in
150. g of X the solution freezes at -8.6 °C instead. Use this information to calculate the molal freezing point depression
constant K, of X.
