A biochemist carefully measures the molarity of salt in 23.5mL of photobacterium cell growth medium to be 7.73 mM. 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 4.78mL. Calculate the new molarity of salt in the photobacterium cell growth medium. Round each of your answers to 3.
