| 31. | The boiling point is 177 �C . The average molar mass is 138.25 g / mol.
|
| 32. | A useful convention for normal laboratory work is to quote molar masses to two decimal places for all calculations.
|
| 33. | The next step is to convert the time at which the samples eluted into a measurement of molar mass.
|
| 34. | To obtain molar mass, light scattering instruments need to measure the intensity of light scattered at zero angle.
|
| 35. | In practice, due to the existence of isotopes, molar masses are used instead when calculating the mass ratio.
|
| 36. | Despite minor differences to define all formulations the predicted molar mass of dry air and below table shows these differences.
|
| 37. | The molar mass distribution of a polymer sample depends on factors such as chemical kinetics and work-up procedure.
|
| 38. | After multiplication with the appropriate molar masses of the batch ingredients one obtains the batch mass fraction matrix M B:
|
| 39. | Where is the molar mass, is the pressure, is the universal gas constant, and is the absolute temperature.
|
| 40. | However, the polymer may be defined by a known precursor or reaction ( s ) and the molar mass distribution.
