The largest ruby in the world is 10.9 cm long, 9.10 cm wide, and 5.80 cm thick, giving it an overall volume of 575 cm3. If the density of ruby—a form of aluminum oxide—is 3.97 g/cm3, what is the mass of the largest ruby?

Respuesta :

Given parameters:

Volume of the ruby = 575cm³

Density of the ruby = 3.97g/cm³

Unknown:

Mass of the largest ruby = ?

Solution:

Density is the mass per unit volume of a substance. It is an intrinsic property of matter that is unique to each of them.

Mathematically;

         Density = [tex]\frac{mass}{volume}[/tex]

Since mass is the unknown;

             Mass = density x volume

Input the parameters and solve;

          Mass = 3.97 x 575 = 2282.75g

The mass of the largest ruby is  2282.75g
