An element with atomic mass Mg*mol^(-1) ...

An element with atomic mass `Mg*mol^(-1)` crystallises in a cubical structure. W g of the element is found to contain n unit cells. How many atoms is its unit cell likely to have? (Assume : Avogadro's number = `N mol^(-1)`)

Text Solution

Verified by Experts

Number of atoms in W g of element = `W/MxxN`
Number of unit cell in W g of element = n
Thus, number of particle in each unit cell = `(WN)/(nM)`
