Respuesta :
The sphere is probably made of silver.
V = ⁴/₃πr^3 = ⁴/₃π(0.40 cm)^3 = 0.268 cm^3
D = m/V = 2.813 g/0.268 cm^3 = 10.5 g/cm^3
The density of silver is 10.5 g/cm^3.
the answer is 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
