ANSWER:
Solution: Here, we are going to calculate the molarity of a solution of acetic acid made by dissolving 20.00 mL of glacial acetic acid in enough water to make 250 mL of solution. Step1: Molarity is defined as the number of moles of the solute(Here acetic acid is the solute) in 1 litre of the solution. Mathematically, Number of moles of solute Molarity(M) = -------------------------------------- ------(1) Volume of solution in litres Step2: In order to calculate molarity
