Question

an experimental procedure you are conducting asks you to measure 90 ml of a solution. which of the following glassware is the best choice for this volume measurement? 100 ml beaker 100 ml erlenmeyer flask 50 ml graduated cylinder 250 ml erlenmeyer flask 100 ml graduated cylinder 250 ml beaker

Explanation:

Beakers and Erlenmeyer flasks are not as precise for measuring volumes as graduated cylinders. A 50 mL graduated cylinder cannot measure 90 mL. Among the options, a 100 mL graduated cylinder is the most appropriate as it has the closest capacity to 90 mL and offers relatively high precision for volume - measurement.

Answer:

100 mL graduated cylinder
