To identify the approximate size of a molecule when run on a gel, using the principle that molecular weight is inversely proportional to migration rate through a gel matrix.

Simply: So we know how long the DNA molecules are.

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.

If you have molecular weight how can you find equivalent weight?

To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
