To determine the density, we use the following formula:
mass= 2.813 grams
volume= ?
we need to first calculate the volume before we can solve for the density. since the question states that the sample has a spherical shape, we can use the volume formula of spheres to find it.
radius (r)=
= 
let's plug in the values
V=
we need to change the
to 
using the following conversion
1 cm= 10 mm
now we can find the density.
density= 2.813 grams/ 0.268 cm= 10.5 g/cm3
mass= 2.813 grams
volume= ?
