Answer 1

Answer:

The density of a metal which crystallises in bcc lattice with unit cell edge length 300 pm and molar mass 50 g mol1, will be

Answer 2

Answer:

given =  BCC lattice i.e. Z = 2  

             length = 300pm

             molar mass = 50 g mol1

to find = mole ?

solution =  

              use the formula = ρ = MZ/ Na³

                                             ρ =  50 x 2 / 6.023 x10²³x( 300 x 10⁻¹⁰)³

                                             ρ =  6.15 g/cm³

so,the answer is   ρ =  6.15 g/cm³.
