Question

What is the density of a 9.0 gram object that displaces 13 cm3 of water?

Answer 1

Density of a substance can be defined as the mass of that substance per unit volume.

`Density = (Mass)/(Volume)`

Given the mass of object = 9.0 g

Volume of the object will be the volume of water displaced by the object

So, volume of the object =
`13cm^(3)`

Calculating the density from mass and volume:

`Density = (9.0 g)/(13 cm^(3))`

= 0.69
`(g)/(cm^(3))`

Therefore, the density of given object is 0.69
`(g)/(cm^(3))`
