Explanation:
molarity (mass %) = 2.5/50 *100
= 5%

Molarity = mass of solute / mass of solution
Mass of solute = 2.5 g
Mass of solution = mass of solute + mass of solvent = 2.5 g + 47.5 g = 50 g
(2.5/50) x 100 = 5
Molarity of solution = 5M
Hope this helped.
Mass of solute = 2.5 g
Mass of solution = mass of solute + mass of solvent = 2.5 g + 47.5 g = 50 g
(2.5/50) x 100 = 5
Molarity of solution = 5M
Hope this helped.
