A biochemist carefully measures the molarity of magnesium ion in 23. mL of cell growth medium to be 67. µM. Unfortunately, a careless graduate student forgets to cover the container of growth medium and a substantial amount of the solvent evaporates. The volume of the cell growth medium falls to 7.2 mL. Calculate the new molarity of magnesium ion in the cell growth medium. Be sure your answer has the correct number of significant digits.
