A metal cube has an edge that is 11.4 mm long and a mass of 6.67 g. Calculate the density of the metal and determine the likely identity of the metal.

d = 4.5 g/cm³

Metal cube is made up off titanium.

Explanation:

Given data:

Edge length of cube = a = 11.4 mm

Mass of metal cube = 6.67 g

Density and identity of metal = ?

Solution:

First of all we will calculate the volume of cube.

V = a³

V = (11.4mm)³

V = 1481.54 mm³

mm³ to cm³:

1481.54 mm³× 1 cm³/ 1000 mm³

1.482 cm³

Density:

d = m/v

d = 6.67 g/ 1.482 cm³

d = 4.5 g/cm³

Metal cube is made up off titanium because density of titanium is 4.5 g/cm³.
