Each of the three beakers contains 25.0 ml
Web50 mL graduated cylinders let you measure volumes up to 50.0 mL to the nearest 0.1 or 0.2 mL, depending on your exact cylinder. Repeat after me: “Erlenmeyer flasks and beakers are not designed to measure volumes,” although they can be used to get a rough estimate if the volume is not critical. For example, if you are making a hot water bath ...
