Osmolarity is a way of expressing solute concentration taking into account whether or not the solute in question dissociates into ions when dissolved in water. For example, suppose a hypothetical salt, AB, completely dissociates Into A and B in water. One mole of AB in water would be one molar (1 M), but it would be 2 osmolar (2 OSM) solution because there would be 1 mole of each ion dissolved in that solution. Thus, osmolarity is the measure of the number of solutes per volume of solution Some salts, ke Naciwa incompletely dissociate into their respective ions when dissolved in water. Using the same principles, one mole of NaCl dissolved in a liter of water would become a molar (M) NaCl solution, but would also be a 1.8 osmolar (1.8 OsM) solution. In the human body, we express this concentration in milliomoles porter (OM) Presuming that the sales tinted below completely dissociato in water, which of the foowing nolution below has the highest osmolarity?
a. 7 M glucose
b. 7m sodium chloride (NACE)
c. A mixed solution of 4 ml NaCl and 3M glucose
d. A mixed solution of 3mM NaCl and glucose
