This video shows a person using an electronic balance and a graduated cylinder to
measure the mass and volume of paper clips. Each dish contains 10 paper clips.
Watch the video, and record the data in the table. Pause and replay the video as
needed. To find the mass of 20 or 30 paper clips, add the mass measurement to the
previous mass measurements.
Density is mass in grams divided by volume in cubic centimeters (cm³). 1 mL is equal
to 1 cm³

Final answer:

The student's question pertains to calculating the density of paper clips by measuring the mass and volume and using the formula Density = Mass/Volume. Even without the video data, the concept explained applies using the formula, where density is a characteristic physical property of a material that remains constant.

Step-by-step explanation:

The student's question revolves around finding the density of paper clips using mass and volume measurements. To calculate the density, one must use the formula Density (D) = Mass (m)/Volume (v). The student is instructed to record the mass of paper clips and measure their volume using a graduated cylinder. Since 1 cubic centimeter (cm³) is equal to 1 milliliter (mL), the student can conveniently measure volume in mL which is numerically equal to cm³ for liquids like water.

For example, to calculate the density of a rock with a mass of 240 grams that displaces 89.0 cm³, the calculation is straightforward: D = 240 g / 89.0 cm³, which yields the rock's density. This method, while simple, is one of the ways to determine density and is a fundamental concept in physics. Even without knowing the exact values of mass and volume from the video the student mentioned, the approach remains the same: measure mass and volume to calculate density, which is a constant characteristic for a given material.
