<h3>What is Molarity? </h3>

Molarity is the amount of a substance in a certain volume of solution. It is defined as the moles of solute per litre of a solution.

Molarity = no of moles / Volume (L)

Where the unit of Molarity is M or moles/ L .

We have given here ,

Molarity→5M

Volume →50 ml

Vol2→25.0 ml

weight of the K I is 3.05 g and molar mass of KI is 166 g/ mol.

M1V1=M2V2

M2= no of moles of KI / Volume

 M2 = 3.05×1000/ 25×166

M2→ 0.73M

V2→5×50×1000/ 0.73

 V2→ 3.24 L

The volume of the solution will be 3.24 L.
