gm NaOH to make 250 ml solution

Answer :

Laiba12345

Answer:

Given Data:

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

The normality of NaOH solution should be 0.02.

Calculation of the normality of NaOH solution:

Since

mass of solute= 0.2

volume of solution: 250ml

So, here

250ml  =0.25dm3   = Volume

m.mass of NaOH= 40g/mol

Now

Equivalent weight of solute=40/1   =40

So, the normality should be

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

N=0.2/40*0.25

N= 0.02
