Question

A block of aluminum occupies a volume of 15ml and weighs 40.5 g, what it its density?

Answer 1

Answer:3
`gmL^(-1)`

Step-by-step explanation:

Let
`v` be the volume of the given material.

Let
`m` be the mass of the material.

Let
`d` be the density of the material.

Density of a material is defined as the ratio of its mass to its volume.

`d=(m)/(v)`

Given,

`m=45g\\v=15ml`

So,
`d=(45)/(15)=3gmL^(-1)`
