The molarity of Ba(OH)₂ barium hydroxide solution is 0.41 M.

<h3>What is Molarity ?</h3>

Molarity (M) is the amount of a substance in a certain volume of solution.

Molarity is defined as the moles of a solute per liters of a solution.

Molarity is also known as the molar concentration of a solution

It can be written as

$\rm Molarity = \dfrac{moles\; of\; solute}{litres\; of \;solution} \\$

The given data is

Mass of Ba(OH)₂ = 3 g

Volume of solution = 42.8 ml = 0.0428 l

Molecular weight of Ba(OH)₂ = 171 g

Moles of Ba(OH)₂ = 3/ 171 = 0.0175 moles

Molarity = 0.0175/0.0428

=0.41 M

Therefore the molarity of Ba(OH)₂ is 0.41 M.
