1kg of `NaOH` solution contains `4g` of `NaOH`. The approximate concentration of the solution is:

1 kg of water contains 4g of NaOH. The concentration of the solution is:

One kilogram of water contains 4 g of NaOH. The concentration of the solution is best expressed as:

Calculate the pH of the solution containing 2g of NaOH per liter of the solution.

0.4g of NaOH is present in one litre of the solution shows that H^(+) concentration of the solution is
