Given : molarity of the solution = 0.2 m
0.2 moles of NaOH are present per liter of the solution.
So no. Of moles of NaOH in 500ml of the solution is : 0.2 x 500ml = 0.2 x 1 = 0.1 m
1 L. 2
Molar mass of NaOH = molar mass of ( NaOH + O + H ) = 23 + 16 + 1 = 40g
So mass of 0.1 mole NaOH = 40 x 0.1 = 4g
