Verified step by step guidance1
Understand the purpose: The problem asks for the laboratory equipment that can accurately measure approximately 50 mL of salt water.
Review the options: Test tubes and beakers are generally used for holding or mixing liquids but are not designed for precise volume measurements.
Consider the Erlenmeyer flask: It is mainly used for mixing and heating liquids, not for accurate volume measurement.
Identify the graduated cylinder: This equipment is specifically designed to measure liquid volumes accurately, with marked graduations for precise readings.
Conclude that the graduated cylinder is the best choice for accurately measuring about 50 mL of salt water due to its precision and volume markings.
