Question

Lead has a density of 11.3 g/`cm^3`. What is the volume of a block of lead with a mass of 282.5 g?

Answer 1

The volume is `"25.0 cm"^3`.

Explanation:

Density equation

`"density"=("mass")/("volume")`

Solution
Rearrange the density equation to isolate volume. Substitute the given values into the equation.

`"volume"=("mass")/("density")`

`"volume"=(282.5color(red)cancel(color(black)("g")))/(11.3color(red)cancel(color(black)("g"))/"cm"^3")` `=` `"25.0 cm"^3"`
