Tobias found a rock that has a mass of 475kg. He placed it in 2000ml of water and the water rose to 2025ml. What is it’s density?

Respuesta :

Given parameters:

Mass of rock Tobias found  = 475kg

Volume of initial water  = 2000mL

New volume  = 2025mL

Unknown:

Density  = ?

Solution:

Density is the mass per unit volume of a substance.

Mathematically;

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

Volume of rock = New volume - Initial volume = 2025 - 2000 = 25mL

Now let us convert the mass to g;

     1000g  = 1kg

       So; 475kg will be 475000g

So;

  Density of stone = [tex]\frac{475000}{25}[/tex]   = 19000g/mL or 19000g/cm³
