Question

A solid object has a mass of 30 grams and a volume of 10 cm3.

Which is the density of the object?

Answer 1

To find the density of an object, you need to use the equation: D = M/V. This is density equals mass over volume.

Mass: 30 g
Volume: 10 cm3

30/10 = 3

Density: 3 g/cm3

Answer 2

Answer: The density of the object is equal to
`3g/cm^3`

Step-by-step explanation:

Density of an object is defined as the ratio of its mass and volume. The chemical equation representing density of an object is:

`\text{Density of an object}=\frac{\text{Mass of an object}}{\text{Volume of an object}}`

We are given:

Mass of an object = 30 grams

Volume of an object =
`10cm^3`

Putting values in above equation, we get:

`\text{Density of an object}=(30g)/(10cm^3)=3g/cm^3`

Hence, the density of the object is equal to
`3g/cm^3`
