A spherical sample has a mass of 2.813 g it has a diameter of 8.0 mm what is the sphere made of

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

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.
