26. A 0.100 g sample of the weak acid HA (molar mass = 100 g/mol) is dissolved in 500 g water.The freezing point of the resulting solution is -0.0056 *C. Calculate the value of Ka for thisacid. Assume molarity equals molality in this solution. (The molal freezing point depressionconstant Kris 1.86 ℃)
