The given

This means 100g solution contains 5g

The density of solution is not known. So the volume of solution can not be found out.

If we assume that the solution being dilute the volume of solution is approximately equal to the volume of solvent water, then we can proceed to calculate the pH of the solution. Taking density of water

The amount of

So the concentrantion of

So the concentration of

So

#=14-log_10=14-log_10[OH^"-"]#

#=14-log_10(25/19)=13.88#
