Question

Using what you have learned, find the volume of the rock. (Hint: For a more precise measurement, use the 25-mL graduated cylinder.)

Options:
A) 10 mL
B) 15 mL
C) 20 mL
D) 25 mL

Answer 1

To find the volume of a rock using a graduated cylinder, fill the cylinder with water, place the rock inside it, and then subtract the initial water volume from the new volume. This difference will give you the volume of the rock.

Step-by-step explanation:

To calculate the volume of a rock using a graduated cylinder, follow these steps:

• Fill the cylinder with a known volume of water and record this initial volume.
• Gently place the rock into the cylinder and ensure it is completely submerged.
• Record the new volume of water with the rock submerged.
• Subtract the initial volume of water from the new volume to determine the volume of the rock.

For example, if the initial volume of water was 15 milliliters (mL) and the new volume with the rock submerged is 21.6 mL, the rock's volume would be 21.6 mL - 15 mL = 6.6 mL. So, by using a 25-mL graduated cylinder and following the correct technique of reading the bottom of the meniscus, we can determine the precise volume of the rock in milliliters.
