At first, calculate the [OH-] because [H+] [OH-] = 1 x 10-14.

Given,

amount of solute = 4 g

molar mass of NaOH = 40 g

Vol. of water = 1000 ml =. 1 litre

Now, applying the formula of Molarity for calculating [OH]- , we get

[OH]- = 4/40 x 1

=0.1 mol/litre

Now,

[H]+[OH]- = 1 x 10-14

[H]+ = 1 x 10-14 / 0.1

=1 x 10-13 M
