An experiment was conducted to determine the density of a rock sample. The table shows a partial record of the experiment. Experimental Record
Mass of Rock
86.59
Volume of Water in the Graduated Cylinder 142.5 mL
?
What information should be recorded in the last row of the table?

the density of the rock

55.91g/ml

Explanation:

The density of the rock after it had being placed in the cylinder of water so the calculation should look like this:

Volume of water substract the mass of the rock:

And that is 142.5 ml - 86.59g =

Answer 55.91 g/ml

So the density of the rock is 55.91g/ml
