Answer: Molarity of a physiological saline solution is 0.15 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
n = moles of solute
=volume of solution in ml
Given : 0.89 g of sodium chloride in 100 ml of solution.
To calculate the moles, we use the equation:
Volume of solution = 100 ml
Molarity of physiological saline solution is 0.15 M
