An element having Bcc geometry has atomic mass 50u. calculate density

1.	An element having Bcc geometry has atomic mass 50u. calculate density of unit cell, if it's edge length is 290pm?
Answer» :TYPE of unit cell : BCCAtomic weight = 50uEdge length = 290pmWe have to find density of unit cell★ Calculations INVOLVING unit cell dimensions :Z DENOTES no. of atoms per unit cella denotes edge length in pmd denotes densityM denotes molar massN_A denotes avogadro's number★ No. of atoms in unit cell :Simple = 1BCC = 2FCC = 4By substituting the given values, we get
