Answer :
The molarity of the KCl solution is 4.04 moles/ litre
What is molarity?
Molarity (M), which is determined by dividing the solute's mass in moles by the volume of the solution in liters, is the most widely used unit to express solution concentration: liters of solution/moles of solute equals M. One liter of a solution with a 1.00 molar concentration (1.00 M) contains 1.00 moles of solute.
The amount of a substance in a specific volume of solution is known as its molarity (M). The number of moles of a solute per liter of a solution is known as molarity. The molar concentration of a solution is another name for molarity.
Molarity = no. of moles/ volume of solution
Volume of KCl solution given is 0.25 L
molarity = 1.01 / 0.25
molarity = 4.04 moles/ litre
