26 июл. 2019 г. · Solution 1. Let's assume there is 1 mole total of solvent and solute. With a mole fraction of 0.2 solute, there is 0.2 mole of solute, ... |
12 июн. 2024 г. · To calculate the molality, multiply the mole fraction by 1000 divided by the molar mass of the solvent, then divide by 1 minus the mole fraction ... |
13 июн. 2018 г. · 1 Answer. Truong-Son N. ... Well, you should assume a certain number of mols of solution. |
The relationship between molality m and mole fraction XA of the solvent is:A. m = XA /1 XA ×1000B. m =1 t u / YOÁ1000C. m =1 X A / XA ×1000/ XBD. m = X A /1 ... |
