Answer : The concentration of luminol in the solution is, 1.20 M.
Explanation : Given,
Mass of luminol = 16.0 g
Volume of solution = 75.0 mL
Molar mass of luminol = 177.16 g/mole
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the concentration of luminol in the solution is, 1.20 M.
