Which tool was most likely used in a procedure if the lab report shows that approximately 300 ml of water was used?

a) a volumetric flask
b) a graduated cylinder
c) a pipette
d) a beaker

Answer : A graduated cylinder

Explanation : A graduated cylinder is most likely to be used for the procedure if the lab report shows that it had approximately 300 mL of water which was used.

Graduated cylinder is the correct answer because it has markings on the cylinder which shows the amount of liquid inside the cylinder. If a 500 mL or a 1000 mL cylinder is used, it would have marking in the range of 10 or 50 mL on the surface of the cylinder. Where the upper or lower meniscus of the liquid can be used to measure the liquid inside the cylinder. In this case, may be the liquid was measured in this cylinder till 300 mL mark.
