Question

Calculate the molarity and osmolality of a 1 L solution containing the following solutes. Assume complete dissociation of all electrolytes.

                                   Molarity (mmole/L)          Osmolality (mOsm/kg/H2O)

  1. 9 g NaCl             _______________             ____________
  2. 100 g Glucose    _______________             ____________
  3. 5 g Urea             _______________             ____________

 

Expert Solution
Definition

Molarity is defined as the number of moles of a solute present per liter of a solution.

Osmolarity is the concentration of osmotically active particles present in solution (osmoles of solute per liter of solution)
