I will teach the method rather just giving out the answer. So firstly, calculate the volume of potassium hydroxide= 28/1000=0.0280dm3 Using in the below formulae: Concentration in mol/dm3 = Amount of solute in mol/ volume in dm3 Here we need to find the concentration ie., the amount of solute. Using the given values we can easily substitute and find the concentration for potassium hydroxide.
