    Option 5. 300 mOsm

    Explanation:

    Osmolarity is the sum of the concentrations of all molecular species that are "swimming" in a solvent. In this case there are two species because the water dissociates sodium chloride in Na + and Cl-. Therefore for each NaCl we will have two independent molecules. Glucose does not dissociate, so osmolarity would not be affected.

    NaCl → Na⁺ + Cl⁻

    0.15 M we have 0.15 moles/L. 2 = 0.30 Osm

    As we have a value of 0.30 Osm, if we convert it to mOsm

    0.30 Osm. 1000 mOsm / 1Osm = 300 mOsm
