Question

tungsten has bcc lattice each edge of the unit cell is 316pm and density of metal
​

Answer 1

Answer:

Calculate the molar mass of tungsten from the given data using

Density= (ZM)÷(a^3 × 6.022 ×10^23)

For bcc Z=2, a= edge length

After u have the molar mass u can find the number of moles of atoms as-

No. of atoms= 50÷M moles

=(50÷M) × 6.022×10^23 atoms

Explanation:

This is the simple way ! if you want brief comment This Answer :)
