F mol mass
WebThe molar mass affects the retention time, or the rate of travel through the column, because if the alcohol being absorbed contains more mass, it will take longer for the mass to be absorbed. For example, methanol, with a mass of 32.05 g/mol, has a retention time of 1.050 minutes: while, ethanol, with a mass of 44.06 g/mol, has a retention time ... WebAnswer: A substance's molar mass is calculated by multiplying its relative atomic mass by the molar mass constant (1 g/mol). The molar mass constant can be used to convert …
