Question

A block is found to have a volume of 35.3 cm^3. it's mass is 31.7 g. Calculate the density of the block.

Answer 1

D = m / V

D = 31.7 / 35.3

D = 0.898 g/cm³

Answer 2

Answer: The density of block is
`0.90g/cm^3`

Step-by-step explanation:

To calculate mass of a substance, we use the equation:

`\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}`

We are given:

Volume of block =
`35.3cm^3`

Mass of block = 31.7 g

Putting values in above equation, we get:

`\text{Density of block}=(31.7)/(35.3cm^3)\\\\\text{Density of block}=0.90g/cm^3`

Hence, the density of block is
`0.90g/cm^3`
