A student was asked to find the density of an unknown object. The student found that the mass of the object was 35.49 g. The student used water displacement to find the volume of the object. The graduated cylinder originally contained 45.1 mL of water. After the object was placed in the graduated cylinder, the volume was 52.3 mL. What is the density of the unknown object? Remember to round your answer to the correct number of significant figures and include the correct units. (Note: 1 mL = 1 cm3)

Answer:

4.29 /mL

Explanation:

density= mass/volume

The density of the unknown object is 4.929 centimeter cube ( cm³ ).

What is density?

Density is the mass of an object in the per unit volume of liquid and can be calculated by dividing the mass of an object to the volume of the object and the unit of density is centimeter cube.

Here, mass of object is 35.49 g and the water displacement to find the volume is 52.3 mL-  45.1 mL = 7.2 ml.

                     

                    Density = mass of object / volume of object

Substituting the value in formula,

                    density = 35.49 / 7.2

                     Density =  4.929 centimeter cube ( cm³ )

Therefore,  4.929 centimeter cube ( cm³ ) is the density of a given object.
