Explain aqueous potassium dichromate

Reference no: EM13292456

A chemist must dilute 71.4mL of 296mM aqueous potassium dichromate (K2Cr6O7) solution until the concentration falls to 81.0mM . He'll do this by adding distilled water to the solution until it reaches a certain final volume. Calculate this final volume, in liters. Round your answer to 3 significant digits.
