On the other hand, the activity of the ith aqueous specie ai can be related to the molality bi (mol of species per kg of H2O) by the activity coefficient γb,i as follows: (23)ai=γb,ibi,(i=1,…,naq) For moderate salinities, the value of molality bi is approximately equal to...
Given that the freezing point for the pure solvent is 79.4 degrees C, the molality is 0.1 m, and the freezing point depression constant is 6.9 degrees C/m, determine the freezing temperature for the n Calculate the freezing point of a 2.6-molal aqueous sucrose sol...
Start with equation (11.96) applied to the apparent molar volume ϕV, solve for V, and differentiate to show that ϕV is related to the partial molar volume of the solute by V¯2=φV+m(∂φV∂m)T,p,n1,where m is the molality (moles of solute per fixed amount of solvent...
