Mendeleev arranged the elements in a table ordered by atomic mass, corresponding to relative molar mass as defined today.

Measurement of colligative properties for a dilute solution of a non-ionized solute such as urea or glucose in water or another solvent can lead to accurate determinations of relative molar masses and of polymers too, which is often not possible.

In addition, he developed the theory necessary to measure molecular weight.

For all practical purposes you can same as the molecular weight.

It is less volatile, however, due to the increase in molecular weight.

The position and sizes of molecular weight standards are indicated.

These methods are used to determine the molecular weight distribution.

The molecular weight was known to be about 78.

The molecular weight of human ceruloplasmin is reported to be 151kDa.

Once the compound's specific class is determined, it's given a number based on its molecular weight.

The end product from chickens has a high molecular weight, which makes it so useful.

To have statistically different peaks there should be a 10% difference between molecular weight.

These agents are made out of high molecular weight polymers.

They are not to be confused with the high molecular weight polymer polybutene-1.

However, in some cases, the molecular weight need not be high to achieve the desired properties.

The stuff has an incredibly high penetration value, for its molecular weight.

Many people believed that such low molecular weight products were all one could hope for from ethylene.

Two molecules might be considered more similar for instance if their difference in molecular weights is lower than when compared with others.

All columns have a range of molecular weights that can be separated.

To make a polymer of high molecular weight a catalyst is needed.

Combining different molecular weights provides some control over the consistency.

This is often used by chemists for the determination of average molecular weight.

The companies primary research focus is into developing low molecular weight Heparins.

High molecular weight and crosslinking are desirable for the same reason.

Molecular weight: The smaller the better, because diffusion is directly affected.

The molecular weight of the species appears as the factor .

I want to find out how many proteins I'm dealing with and what their approximate molecular weight is.
