Calculate the density of the rock if its mass is 360 g.

12.0 g/mL

Explanation:

From the question given above, the following data were obtained:

Mass of Rock = 360 g

Volume of water = 150 mL

Volume of water + Rock = 180 mL

Density of Rock =?

Next, we shall determine the volume of the rock. This can be obtained as follow:

Volume of water = 150 mL

Volume of water + Rock = 180 mL

Volume of Rock =?

Volume of Rock = (Volume of water + Rock) – (Volume of water)

Volume of Rock = 180 – 150

Volume of Rock = 30 mL

Finally, we shall determine the density of the rock as illustrated below:

Mass of Rock = 360 g

Volume of Rock = 30 mL

Density of Rock =?

Density = mass /volume

Density of Rock = 360 / 30

Density of Rock = 12.0 g/mL

Thus, the density of the rock is 12.0 g/mL

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
