Answer #1

We know molarity of solution is defined as number of moles of solute dissolved per litre of solution.Molarity is the property which gives concentration o particular species in solution.

From above question we can infer information that Excess KCl is being dissolved in AgNO3 solution to yield 0.273 g of precipitate.

So here as KCl is in excess so remaining of it will get precipiated

Hence number of moles of KCl=0.273/74.5=3.66*10-3

Volume of AgNO3 solution=56.3ml=0.0563 litres

So Molarity=3.66*10-3/0.0563=0.065 M
