A large diamond with a mass of 481.3 grams was recently discovered in a mine. if the density of the diamond is 3.51 grams over c
agasfer [191]

The volume of the diamond is 137.1 cm³. The correct option is the last option 137.1 cm³

<h3>Density, Mass and Volume </h3>

From the question, we are to calculate the volume of the diamond

Using the formula,

Density = Mass/ Volume

Then, we can write that

Volume = Mass/ Density

From the given information,

Mass of the large diamond = 481.3 grams (g)

Density of the diamond = 3.51 grams/ centimeters cubed (g/cm³)


Putting the parameters into the formula, we get

Volume = (481.8 g)/ (3.51 g/cm³)

Volume = 137.1225 cm³

Volume ≈ 137.1 cm³

Hence, the volume of the diamond is 137.1 cm³. The correct option is the last option 137.1 cm³
