Question

What is the concentration of a solution prepared by diluting 25.0 mL of a 4.50 M H₂SO₄ solution to a final volume of 1.00 L?

Answer 1

Before dilution After dilution concentration (mi) = 4.50 m Volume (vi) = 25.0 ML concentration (MA) = ? Volume (VA) = 1000 ML since, the dilution does not change the number of mole of add. Therefore, No. of mole of acid before dilution No. of mole of acid . after dilution. (molarity x volume); = (molarity & volume) Mivi - MAVE : Mo = Mivi = 4.50 MX 25,0 mL 1000 mt 10.1125 ml of solution after dilution Therefore, the concentration is 0.1125 Mi
