What is protein marker and what is its use in electrophoresis?
it is a marker for specific protein identification.in electrophoresis it is used to identify particular protein based on the molecular weight.
How do you calculate the molecular weight and the uncertainty of the molecular weight of a unknown solute using propagated error?

How do you calculate ppm from molecular weight?
ppm is parts per million and thus a concentration. It can not be calculated from molecular weight.
When is DNA cut during electrophoresis?
Electrophoresis technique is not designed to cut DNA molecule. When DNA is analyzed by electrophoresis to determine its molecular mass, the molecular biology engineer usualy digests the DNA molecule, before the electrophoresis, with specific enzymes called "restriction enzymes" in order to obtain fragments of diverse molecular weights that can be seen as bands in electrophoresis gels.
How to calculate empirial formula from molecular formula?
Calculate the empirical formula weight. Find the ratio of the molecular weight to the empirical formula weight. (n= molecular weight/ empirical formular weight). Multiply each subscript of the empirical formula by n.

Will two molecules having the same molecular weight and charge have the same mobility in electrophoresis?
yes...!
Why do you need a molecular weight ruler alongside your samples during electrophoresis?
A molecular weight ruler uses a sample of fragments of a known size (known as a molecular weight marker) to be placed alongside the experimental and control samples. It helps compare the migration distance of the experimental fragments to the migrating distance of the fragments of a known size that make up the molecular weight marker. Then the scientist can calculate an approx. size of their experimental samples.
How do you calculate density from molecular weight?
the given molecular weight is divided by volume
One lane of an electrophoresis gel shows a 100bp ladder. What is the purpose of this ladder?
It is used as a marker for molecular weight.

How do you calculate number average molecular weight given molecular weight range and fraction?
Molecular weight is just an older term for molar mass. They are the same.

Do you need to know atomic weight to calculate molarity?
Yes, you definitely need to know the molecular weight of a compound to calculate molarity.
Calculate the amount in moles 16.3gSF6?
So here, you have to divide by the molecular weight. The molecular weight is 146g/mol. 16.3/146 is 0.11164 moles
