Question

Lead has a density of 11.3 g/cm3 and a mass of 282.5 g. What is its volume? a. 2.5 cm3 c. 250 cm3 b. 25 cm3 d. 2500 cm3

Answer 1

`(282.5)/(11.3) = 25`

The volume is 25
`cm^(3)`

Answer 2

Answer : The correct option is, (b)
`25cm^3`

Solution : Given,

Mass of lead = 282.5 g

Density of lead =
`11.3g/cm^3`

Formula used :

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

Now put all the given values in this formula, we get the volume of lead.

`11.3g/cm^3=\frac{282.5g}{\text{Volume of lead}}`

`\text{Volume of lead}=25cm^3`

Therefore, the volume of lead is,
`25cm^3`
