Question

Concept:

Graduated cylinder: A graduated cylinder is a glass cylinder with calibrated volume markings on the side designed to measure the volume of liquid contained. The accuracy depends on its size, but for small graduated cylinders, like 10 mL or 25 mL, it is around 0.1 mL.

Beaker and Erlenmeyer flask: Beakers and Erlenmeyer flasks are designed to hold solutions and are not used to measure accurate volumes of liquids. The accuracy of the markings on a beaker is ±10%. Beakers and Erlenmeyer flasks can be used for approximating volumes when accuracy is not required.

Volumetric flask: Volumetric flask has one mark on its neck. When filled to the mark, the flask contains its designed volume to the nearest 0.01 mL. This is one of the most accurate volumetric equipment in the laboratory

Question:

To accurately measure 25 mL of water, which is the best volumetric glassware to use?

A 25.00 mL volumetric flask

A 25 mL graduated cylinder

A 50 mL graduated cylinder

A 50 mL volumetric flask

Explanation / Answer

Answer – From the given definition of the we got the more accuracy of the measuring the volume is with volumetric flask, since it has accuracy measuring the volume up to 0.01 mL, which is more than other glassware.

So for the accurately measure 25 mL of water we need a 25.00 mL volumetric flask, which is the best volumetric glassware to use
