Question

24) An 0.89 percent w/ NaCl solution is referred to as physiological saline solution What is the osmolarity (osmol) of this solution? (Spts)

Answer 1

A mole of NaCl dissociates fully in water to yield two moles of particles: Na+ ions and Cl- ions. Each mole of NaCl becomes two osmoles in solution.

Nace in 1 litre of 0.89.). WIV Nach means & water es of Nach = 8.9 g 0.152 moles 0.152 moles 58.44 gmo or 152 m moles Nall - Natte- I moles dissociate into Imole each of Nat & ce 152 mmoles in - 152 mmoles of Nat 4 152 mmole ce a Osmolarity = no. of moles of Electrolytes (Total) Volume of solution in L = (152 +152) mmoles= 304 m Osmol/L I Lite

Therefore the answer is 304mOsmol/Litre
