Question

Edge of a aluminium cube is 0.18 cm. If density of aluminium is 2.70g/cc. Calculate its mass. urgent answer

Answer 1

use the given formula below.z stands for no of atoms in unit cell

Answer 2

Hi friend !!!

Radius = 0.18 cm

Volume of the sphere = 4/3πr³
= 4/3 × 3.14 × (0.18)³
= 0.0244 cm³ ( approx.)

Density = 2.70 g / cm³

Density = Mass / Volume

Mass = Density × Volume
= 2.70 × 0.0244
= 0.06588 Grams
