Question

5. Convert the following temperatures: 37.2 F - "C 49.5°C - K 6. A student measured the following mass and volume data for various sized samples of the same material Mass (9) 1.55 2.10 3.15 3.85 4.20 5.15 7.00 Volume (mL) 0.22 0.30 0.44 0.54 0.59 0.73 0.99 Plot the data on the grid below with mass on the y-axis and volume on the x-axis. Label your aces including units, and provide a title for the graph. Use a ruler to draw the best fit line through the data and determine the slope of this line. Show all work. What is the density of this material?

Title for the goofbh cis :- Imous and wokime Relationship / slope of line :- Take any two point in the graph and point out their cordinates. Then, islope is given U slope 9-4, slope48-3.2 badis -(7.33 1 x2-x 0.68 -0.53

som (0.68,4.8) masựf sample (ams) 0.53,3.7) o 1.5 Ø volume of sample (mL)
Density is given by the mass/volume.

And the slope of the graph is actually mass is divided by the volume of the sample.

So the density is 7.33 g/ml.

For calculation of density you can also take any point on the line in graph and divide y/x which actually mass/volume.
