a solution of 0.1M NaOH has been prepared.How would you make 1L of the same solution
Dissolve 4 g analytical grade NaOH in 1 L demineralized water at 20 oC, using a volumetric flask.
It is possible only if you evaporate the water.
we need 0.8gm NaoH and dissolved in 10 ml of water to make 2N solution of NaoH .

If you think to a 2 M solution dissolve 80 g NaOH in 1 L demineralized water at 20 0C.
NaOH and H2O form a solution of Na+(aq) and OH-(aq) ions (the solvent water, aq, is written as subscripted (aq) ) To make 1 Normal solution you need to know the equivalent of NaOH, which is calculated by dividing Molecular weight by 1, that is 40 divided by 1= 40. So the equivalent weight of NaOH is 40. To make 1 N solution, dissolve 40.00 g of sodium hydroxide in water to make volume of 1 liter.
Take 2.409 ml of 3.05M NaOH mix c a balance of H2O to form 50ml of mixture
This solution contain 26,3 g NaOH.

The answer is 0,625 moles.
The concentration of this solution (in NaOH) is 40 g/L.
