21. Using multiple standards, a calibration curve of time versus molar mass can be developed. 22. :Please see Molality and Molar mass . 23. By variation of the catalyst concentration the molar masses of the synthesized polymers could be adjusted. 24. Using these equations one can calculate the molar mass of solutes from the osmotic pressure data. 25. In the same conditions of temperature and pressure, the molar mass is proportional to the mass density. 26. Where \ varrho is the density of the solution, and M _ i are the molar masses . 27. Through the procedure called ebullioscopy, a known constant can be used to calculate an unknown molar mass . 28. Other than monodisperse polymers, there is normally a molar mass distribution caused by chains of different length. 29. :The molar mass is wrong too, but it looks like it can't be fixed. 30. The boiling point is 137 �C . The average molar mass is 110.20 g / mol.
