With this given information and the procedure, how would we write a new data table of our own "filled with our findings" without doing the experiment?

Question

how would we collect the data we need from the experiments without doing the experiments at home? The data table below has provided data from another persons experiment . ANd now we have to make a new table, using our own findings, without doing the experiment. we have an unknown solution b, and are testing density and boiling point to identify the unknown solution against the six given Solutions. The procedure is

1.. Weigh and record the weight of a 10 ml graduated cylinder

2.transfer 5 ml if the unknown liquid into the 10 ml graduated cylinder

3.weigh and record the weight of the graduated cylinder with the unknown liquid

4. Record the volume of the unknown liquid

5.calculate the density of the liquid

6. Carefully clean out the graduated cylinder and repeat the procedure two more times.

BOILING POINT 

1.Using a 500mL beaker, make a hot water bath.

2. On the heating pad, start heating the water in the beaker.

3. In a clean, dry test tube, collect a 10mL sample of the unknown solution.

4. Put a constant volume of solution in a test tube and place it in a hot water bath.

5. Using a thermometer, determine the liquid's temperature.

6.During the heating process, take a temperature reading of the sample in the test tube every 10-20 seconds.

7.Record the temperatures for the initial formation of bubbles up until the solution reaches a steady boil.

8. Keep an eye out for signs of boiling, noting the temperature of the unknown.

9. Once it starts to boil, turn off the heating plate, and record the temperature, and note it down in the table. 

10. Clean up, and repeat process 2 more times.

Answer 1

My first thought is that you have the instructions wrong. I don't think you are to "do" the experiments outlined in the procedure but use the procedures to construct lines in a data table.

For example,

The first line in the data table would read "mass of an empty 10-mL graduated cylinder" with columns for each of the given materials you are working with.

the second line in the data table would read "mass of graduated cylinder with 5.00 mL liquid"

You would then add a line to determine the mass of the unknown liquid and an fourth line to determine the density of the unknown liquid.

You would do something similar for the boiling point of the liquid.

Then use the information given to determine the identity of the unknown (listed as "B" in your information).

The data for the various liquids and the unknown are given to you so you just have to fill in the blanks for density and boiling points; then use the data to determine the identify of the unknown.
