Answer 2

Answer:

ANSWERMolarity (M) : The number of moles of a solute dissolved in 1 L (1000 ml) of the solution is known as the molarity of the solution.Molarity of a solution(M)= molar mass of solutemass of solute × volume of solution in mL1000 ∴0.2= 40w × 5001000 so w=4gm.Amount of sodium hydroxide present in 500ml of 0.2M solutions is 4 gm.
