Question

What is the density of a substance that has a mass of 90 g and a volume of 18 cm3?

Answer 1

`\boxed{\tt d=5g/cm^3}`

Step-by-step explanation:

The density of a substance can be found using the following formula.

`d=(m)/(v)`

where
`m` is the mass and
`v` is the volume.

The mass of this substance is 90 grams and the volume is 18 cubic centimeters.

`m= 90 g \\v= 18 cm^3`

Substitute the values into the formula.

`d=(90 g)/(18 cm^3)`

Divide 90 grams by 18 cubic centimeters.

`d=5 g/cm^3`

The density of the substance is 5 grams per cubic centimeter.
