Molar Mass (Molecular Weight) - The term mole also referred to as mol was first used by Ostwald in 1896. The mass in g of 1 mole of a substance is known as the molar mass or molecular weight of the substance. The molar mass of any substance can be calcul
In order to normalize the polymer property with its molar mass the intrinsic viscosity is determined by extrapolation of reduced viscosity to zero mass concentration [6]. We may now establish an activity coefficient relative to the extreme value. Assume that disintegration of the stacked asphaltene ...
