A biochemist carefully measures the molarity of ammonium chloride in 75.3 mL of photobacterium cell growth medium to be 44.0 µM. Unfortunately, a careless graduate student forgets to cover the container of growth medium and a substantial amount of the solvent evaporates. The volume the cell growth medium falls to 5.13 mL. Calculate the new molarity of ammonium chloride in the photobacterium cell growth medium. Be sure your answer has the correct number of significant digits.
