Answer:
1.13 M
Explanation:
Given data
- Mass of luminol (solute): 15.0 g
- Volume of solution = volume of water = 75.0 mL = 0.0750 L
- Molar mass of luminol: 177.16 g/mol
The molarity of the stock solution of luminol is:
M = mass of solute / molar mass of solute × liters of solution
M = 15.0 g / 177.16 g/mol × 0.0750 L
M = 1.13 M

Boyle's law :- the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature.
Boyle's law can also be formularized as P1V1 = P2V2
Charle's law :- the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant.
Charle's law can also be formularized as V1/T1 = V2/T2
