How to find density with radius, height, and mass.

1 answer:

4 0

The mass density ρ of an object may be found by dividing its mass M by its volume V. Sphere: V = (4/3) π R3 where R is the radius of the sphere. Cylinder: V = π R2L where R is the radius of its base and L the length of it.

Answer:

$Density = 8.92 \ g/mL$

Explanation:

The equation for density is:

$Density = \frac{mass}{volume}$

We plug in the given values:

$Density = \frac{12.93 \ g}{1.45 \ mL}$

$Density = 8.92 \ g/mL$
