When an irregularly shaped chunk of an unknown metal with a mass of 25.32 g was placed in a graduated cylinder containing 25.00 mL of water, the water level in the cylinder rose to 28.22 mL. What is the density of this unknown metal?

Respuesta :

Answer: The density of the unknown metal is 7.86 g/ml.

Explanation:

Density is defined as the mass contained per unit volume.

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

Given : Mass of metal  = 25.32 g

Volume of metal = volume of water displaced = (28.22 - 25.00) ml = 3.22 ml

Putting in the values we get:

[tex]density=\frac{25.32g}{3.22ml}[/tex]

[tex]Density=7.86g/ml[/tex]

Thus the density of the unknown metal is 7.86 g/ml
