Answer :
the molarity of the perchloric acid solution is 0.10M
What is molarity ?
The molarity of a solution is the quantity of solute in moles per litre of solution. Molarity is represented by a capital M.
A solution is a combination of two or more compounds in chemistry in which neither substance undergoes chemical change. For instance, salt water is a mixture of salt and water (the solvent) (the solute). The amount of dissolved material in a solution is known as concentration. In other words, it refers to how much substance has been added to your liquid. Usually, molarity is used to express concentration.
In chemistry, a mole is a fundamental unit. It is the mass of a substance (6.02 x 1023) in grammes that contains the same number of atoms, molecules, or ions as 12 grammes of carbon-12.
We know
M1*V1 = M2*V2
M1 = molarity of barium chloride
V1 = volume of barium chloride
M2 = molarity of perchloric acid
V2 = volume of perchloric acid
0.166*16 = N2*25.6
M2 = 0.10M
the molarity of the perchloric acid solution is 0.10M
