How can I calculate osmolarity of NaCl?
2 Answers
This is simply twice the molarity of
Explanation:
Osmolarity is simply the concentration of all ions in solutions. It is thus the sum of sodium ion and chloride ion concentrations, inasmuch as as sodium chloride is a strong electrolyte, and dissolves to give stoichiometric
You multiply the molarity of the
Explanation:
An osmole (Osmol) is a mole of particles that contribute to the osmotic pressure of a solution.
For example,
Each ion contributes to the osmotic pressure of the solution.
Thus, each mole of
A solution of 1 mol/L
EXAMPLE
Calculate the osmolarity of 0.140 mol/L
Solution
Each mole of
∴
