Question

Cork has a relative density of 0.25. What is the the volume in cubic centimeters of 50g of cork ? Take the density to be 1000 kg/m^3.

Answer 1

`"The volume is " 2*10^4 m^3`

Explanation:

This "Take the density to be 1000 kg/m^3" is strange. You probably wonder "density of what?". I recognize 1000 kg/m^3 to be the density of water.

"Relative density" is a phrase I am not familiar with, but it must mean that cork's density is 1/4 of water's density. So that would be 250 kg/m^3.

For this problem, rearrange density=mass/volume to
volume = mass/density

`"volume" = (0.05 kg)/(250 (kg)/m^3) = 2*10^4 m^3`

I hope this helps,
