Answer:
The molarity of methylene blue is 1.5 × 10⁻⁵ M
Explanation:
When we talk about aqueous solutions, 1 ppm means 1 mg of solute per liter of solution. We need to express this concentration in molarity, which is moles of solute per liter of solution. To convert mass to moles we need the molar mass of methylene blue(MB), which is 320 g/mol.
Then,
