The number of atoms per cubic meter in aluminum is 6.04 x 10²².
"Density is the mass per unit volume. Density is a scalar quantity. It is denoted by d and the symbol for density is given as rho, a Greek symbol. Density is calculated as mass divided by volume."
The density of Al is 2.71 g/cm3
The atomic weight of Aluminum is 26.98 g/mol.
The Avogadro's number is 6.023 x 10²³
To find the number of atoms per cubic meter
N = ρNa / A
N = 2.71 x 6.023 x 10²³ / 26.98 = 6.04 x 10²²
Thus, the number of atoms per cubic meter in aluminum is 6.04 x 10²².
