If you add 25.0 mL of water to 125 mL of a 0.150 M LiOH solution, what will be the molarity of the resulting diluted solution?

Concentration is the number of moles of solute in a fixed volume of solution

Concentration(c) = number of moles of solute(n) / volume of solution (v)

25.0 mL of water is added to 125 mL of a 0.150 M LiOH solution and solution becomes more diluted.

original solution molarity - 0.150 M

number of moles of LiOH in 1 L - 0.150 mol

number of LiOH moles in 0.125 L  - 0.150 mol/ L x 0.125 L = 0.01875 mol

when 25.0 mL is added the number of moles of LiOH will remain constant but volume of the solution increases

new volume -  125 mL + 25 mL = 150 mL

therefore new molarity is

c = 0.01875 mol / 0.150 L  = 0.125 M

answer is 0.125 M

In the given question according to the information the process of polymerization is an addition polymerization.

<h3>What is polymerization?</h3>

Polymerization is a process in which addition of many small molecules takes place for the formation of a large three dimensional substance known as polymer.

In the polymerization of polyethene the small repeating molecule is ethene and in this process product formed due to the addition process to the double bond of the ethene.

  • In condensation polymerisation removal of water molecule or any other molecule takes place.
  • In dehydrogenation polymerisation removal of hydrogen molecule takes place.
  • In dehydrohalogenation polymerisation removal of hydrogen halide molecule takes place.

Hence given process is an addition polymerisation.
