Question

part e
carry out these steps, and record the findings in the table.

1. use the gram scale to measure the mass of 2, 4, and 6 paper clips.
2. fill the graduated cylinder with 8.0 ml of water.
3. add 2 paper clips to the water in the graduated cylinder. determine how much the volume of water increases. this increase in volume is the volume of the paper clips. record the value.
4. repeat this process to find and record the volume of 4 paper clips and then 6 paper clips.
5. density is mass in grams divided by volume in cubic centimeters (cm³). one ml is equal to 1 cm³. calculate and record the density of the steel used in the paper clips.

number of paper clips mass volume density
2
4
6

Explanation:

Step1: Measure mass

Use gram - scale to measure mass of 2, 4, 6 paper - clips. Let the masses be $m_2$, $m_4$, $m_6$ respectively.

Step2: Measure volume

Fill graduated cylinder with 8.0 mL water. Add paper - clips one by one. Let the volumes of 2, 4, 6 paper - clips be $V_2$, $V_4$, $V_6$ respectively, measured by the increase in water volume.

Step3: Calculate density

For 2 paper - clips, density $
ho_2=\frac{m_2}{V_2}$ (since $1\ mL = 1\ cm^3$).
For 4 paper - clips, density $
ho_4=\frac{m_4}{V_4}$.
For 6 paper - clips, density $
ho_6=\frac{m_6}{V_6}$.

Answer:

Record $
ho_2$, $
ho_4$, $
ho_6$ in the table for 2, 4, 6 paper - clips respectively.
