Calculate the normality of NaOH solution Formed by dissolving 0.2

gm NaOH to make 250 ml solution

Given dа ta:

mass of solute = 0.2

volume of solution: 250ml

Normality=?

Explanation:

250ml = 0.25dm3 Volume

m. mass of NaOH = 40g/mol

Equivalent weight of solute=40/1 = 40

N=mass in g of solute/equivalent weight of solute*Volume of solution

N=0.2/40*0.25

N = 0.02
