Question

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

1. pour water to the 2.0 ml mark in the graduated cylinder. if you look at the graduated cylinder from the side, you will see the water forms a curve. make sure the bottom of the curve is at the 2.0 ml mark.
2. use the gram scale to measure the mass of the graduated cylinder and 2.0 ml of water. record the mass in the table. calculate the mass of 2.0 ml of water by subtracting the mass of the graduated cylinder.
3. repeat this process to find and record the mass of 4.0 ml of water and then 6.0 ml of water.
4. density is mass in grams divided by volume in cubic centimeters (cm³). 1 ml is equal to 1 cm³. calculate and record the density of water.

volume of water mass of graduated cylinder and water mass of water density
2.0 ml
4.0 ml
6.0 ml

Explanation:

Step1: Recall density formula

The density formula is $
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass and $V$ is volume. Also, $1\ mL = 1\ cm^{3}$.

Step2: For 2.0 mL of water

Let the mass of the graduated - cylinder be $m_{cylinder}$ and the mass of the graduated - cylinder + 2.0 mL of water be $m_{total1}$. Then the mass of 2.0 mL of water $m_1=m_{total1}-m_{cylinder}$. The volume $V_1 = 2.0\ cm^{3}$. The density $
ho_1=\frac{m_1}{V_1}$.

Step3: For 4.0 mL of water

Let the mass of the graduated - cylinder + 4.0 mL of water be $m_{total2}$. Then the mass of 4.0 mL of water $m_2=m_{total2}-m_{cylinder}$. The volume $V_2 = 4.0\ cm^{3}$. The density $
ho_2=\frac{m_2}{V_2}$.

Step4: For 6.0 mL of water

Let the mass of the graduated - cylinder + 6.0 mL of water be $m_{total3}$. Then the mass of 6.0 mL of water $m_3=m_{total3}-m_{cylinder}$. The volume $V_3 = 6.0\ cm^{3}$. The density $
ho_3=\frac{m_3}{V_3}$.
In an ideal situation (at standard temperature and pressure), the density of water is approximately $1\ g/cm^{3}$. You would fill in the table by first measuring the masses of the graduated - cylinder with different volumes of water, subtracting the mass of the empty graduated - cylinder to get the mass of water, and then using the density formula to calculate the density for each volume.

Since the actual values of the masses of the graduated - cylinder and the graduated - cylinder with water are not given, we can't provide numerical answers for the table. But the process to fill the table is as described above.

Answer:

Follow the steps above to fill the table with measured and calculated values. For the density values, they should be close to $1\ g/cm^{3}$ if the experiment is done accurately at standard conditions.
