Question

What is the difference between molarity and osmolarity?

1) Molarity refers to moles per liter and osmolarity refers to grams per 100 ml
2) Molarity is used for solutes added to water and osmolarity considers any dissociation that may occur in water.
3) Molarity is more accurate to use when referring to solute concentration in body fluids
4) All of the above are TRUE statements

Answer 1

Molarity is used for solutes added to water, while osmolarity considers any dissociation that may occur in water.

Step-by-step explanation:

Molarity is defined as the number of moles of a solute dissolved in one liter of solvent, or (moles/L). While osmolarity is a measure of the total concentration of solutes in a solution, taking into account the dissociation of solutes into ions. It is important to note that molarity is used specifically for solutes added to water, while osmolarity considers any dissociation that may occur in water.

Therefore, the correct statement that differentiates molarity and osmolarity is:
2) Molarity is used for solutes added to water and osmolarity considers any dissociation that may occur in water.
