Answer: The molarity of the solution is 0.26M
Explanation: Molarity of the solution is defined as the number of moles of solute present in a liter volume of solution.
Number of moles is expressed by using the formula:
Putting this in above equation, we get:
Given mass of solute (NaOH) = 5.20 g
Molar mass of solute (NaOH) = 40 g/mol
Volume of solution = 0.500 L
Putting values in above equation, we get:
