A piece of metal is in the shape of a cylinder with the height of 5.62cm and a diameter of 1.34cm. If the magnesium sample has the mass of 13.77g,

Question

what is the density of the sample 

 

Answer 1

M = mass = 13.77 g

 

d = diameter = 1.34 cm

 

h = height = 5.62 cm

 

V = volume = (πd²/4)h

 

ρ = density = M/V = M / [(πd²/4)h]

 

You know M, d, and h.  Just plug in the numbers and get density in g/cm³.  You can finish from here.
