Question

Students are measuring the volume of an irregular solid using a graduated cylinder. They place the solid into the cylinder which already contains 50.2 mL of water, and the water level rises to 75.4 mL. Calculate the volume of the irregular solid to the nearest tenth of a mL.

A) 25.2 mL
B) 25.0 mL
C) 24.8 mL
D) 25.4 mL

Answer 1

To find the volume of the irregular solid, subtract the initial water level from the final water level in the graduated cylinder, resulting in 25.2 mL. Therefore, the correct answer is A) 25.2 mL.

Step-by-step explanation:

To calculate the volume of an irregular solid using a graduated cylinder, subtract the initial water level from the water level after the solid has been immersed. In the question provided, the initial water level is 50.2 mL and the water level rises to 75.4 mL after placing the solid in the cylinder.

By subtracting the initial volume from the final volume (75.4 mL - 50.2 mL), we can find the volume of the irregular solid. The calculation gives us 25.2 mL, which means the volume of the irregular solid is 25.2 mL when rounded to the nearest tenth of a milliliter.

Therefore, the correct answer is A) 25.2 mL. When measuring with a graduated cylinder, always remember to read the bottom of the meniscus and estimate to the nearest tenth of the smallest scale division, which in most cases is 0.1 mL.
