How can you determine the atomic mass of an unknown metal if you know its density and the dimension of its unit cell? Explain?

Explanation

Ans: Let the edge length of the unit cell:=a and the number of atoms
per unit celi .=z. Atomic mass of the element .=M. Density of the unit ceil .= mass of the unit cell / volume of the.unit cell ..= number of atoms in thé unit cell xx mass of each atom /a a^3=z xx m/a^13.Atomic mașs .M=. mass of .N_0(6.02 xx 10^23). .atoms masss of one atom .dotm=M/N_0.
.therefore. density .rho=Z M/N_0 a^3 therefore..M=rho N_n a/Z.
