Calculate the density of an object with a mass of 3.8 g, that when placed in a 10.0 mL graduated cylinder with an initial volume of 4.5 mL rises to a final volume of 8.6 mL. *

Answer : The density of an object is 0.93 g/mL

Explanation : Given,

Mass of an object = 3.8 g

Initial volume = 4.5 mL

Final volume = 8.6 mL

First we have to calculate the volume of an object.

Volume of an object = Final volume - Initial volume

Volume of an object = 8.6 mL - 4.5 mL

Volume of an object = 4.1 mL

Now we have to calculate the density of an object.

Formula used:

Now putting all the given values in this formula, we get:

Therefore, the density of an object is 0.93 g/mL

c is the answer because when something is left after something evaporates that shows the chemical change.
