300mOsM
The mOsM helps in defining the osmolality which is the number of solutes present per kilogram within a particular concentration of solution. When the osmolality value is high, it means that there is high number of dissolved solute particles in the solution and when the osmolality is lower, it means that solution is more diluted and has low number of solutes. In this case, the 300mOsM valued solution have high osmolality as it has higher number of solute particles present within it as compared to the solution that has an osmolality of 100mOsM.
