Volume of Water - Volume of Water * Object =
Mass of Object
60 ml
73.5 ml
51.3 g
Density

3.8 g/mL

Explanation:

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

Volume of Water = 60 mL

Volume of Water + Object = 73.5 mL

Mass of object = 51.3 g

Density of object =?

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

Volume of Water = 60 mL

Volume of Water + Object = 73.5 mL

Volume of object =?

Volume of object = (Volume of Water + Object) – (Volume of Water)

Volume of object = 73.5 – 60

Volume of object = 13.5 mL

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

Volume of object = 13.5 mL

Mass of object = 51.3 g

Density of object =?

Density = mass /volume

Density of object = 51.3 /13.5

Density of object = 3.8 g/mL

Thus, the density of the object is 3.8 g/mL
