A biochemical engineer isolates a bacterial gene fragment and dissolves a 10.0-mg sample in enough water to make 30.0 mL of solu
Novay_Z [31]

The molar mass of the gene fragment is 19182 g/mol.

What is osmotic pressure ?

Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in a pure solvent by osmosis. Potential osmotic pressure is the maximum osmotic pressure that could develop in a solution if it were separated from its pure solvent by a semipermeable membrane.

We employ the osmotic pressure equation to determine the solute's concentration, which is:

π = iMRT

Using the values in the equation above, we obtain:  19182 g/mol.
