How to solve for osmolarity

WebOsmolarity is an old term for osmotic concentration. This can be used to measure the amount of solute (think sugar) dissolved in a solvent (water). If the level of solute of a solution is higher than the concentration of solute inside of the cell, water will flow out of the cell during osmosis. See egg in syrup in the video below. WebThe meaning of OSMOLARITY is the concentration of an osmotic solution especially when measured in osmols or milliosmols per liter of solution.
