A student was assigned the task of determining the identity of an unknown liquid. The student weighed a clean, dry 250-mL Erlenmeyer flask. The student completely filled the flask with water. He then proceeded to weigh the flask containing the water. Mass of 250-mL Erlenmeyer flask: 78.639 g Mass of 250-mL Erlenmeyer flask and water: 327.039 g Assuming the density of water is 1.00 g/mL at ambient temperature, what is the exact volume (in mL) of the 250-mL Erlenmeyer flask?
