The molar mass of a substance is the amount of grams there are in a mole (the units for molar mass are grams/mole). Finding the molar mass of an element or compound is not as hard as it might seem: the only things that you need to know are which elements are involved and how many of them are present.

As shown in this video, we can obtain a substance's molar mass by summing the molar masses of its component atoms. We can then use the calculated molar mass to convert between mass and number of moles of the substance. Molar mass (M) has a significant effect on the rheological properties of polymer melts and hence on their processing performance. At low molar mass, i.e., below some critical molar mass (M c), for flexible chain polymers η 0 depends on M w, while above M c, η 0 depends on M w to the 3.4 to 3.6 power for most flexible linear polymer chains: Molar mass (M) has a significant effect on the rheological properties of polymer melts and hence on their processing performance.At low molar mass, i.e., below some critical molar mass (M c), for flexible chain polymers η 0 depends on M w, while above M c, η 0 depends on M w to the 3.4 to 3.6 power for most flexible linear polymer chains: To know the relationship you first need to know what is molarity. So ,mathematically molarity is written as Molarity=no.of moles/volume of solution(In L) Or M=n/V And n=w/m where w= given mass and m= Molar mass Now if we substitute this value of n Molar mass is the mass of a mole of a substance, whether it is an element or a compound.

The molar mass is measured in grams per mole (g/mol). In general, the molar mass is the ratio of the mass of the substance to the number of particles present in it. The molar mass of an element is equal to its Molar mass is the mass of a given substance divided by the amount of that substance, measured in g/mol. For example, the atomic mass of titanium is 47.88 amu or 47.88 g/mol.

The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol = 1.000000 g/mol. For normal samples from earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight or the conventional atomic weight.
