Calculate the number of unit cells in 3 gram metal that crystallises to simple cubic unit cell having edge length 336 pm. (density of metal =9.4 g cm^-3 )

Question

Accepted Answer

Correct answer: A. (a) : Volume of the unit cell = (336 pm )^3 =(336 10^-10 cm)^3=3.8 10^-23 cm^3 Volume of 3 g of the element = Mass Density = 3 g9.4 g/ cm^3=0.32 cm^3 ∴ Number of unit eells in this volume = 0.323.8 10^-2.3=0.0842 10^23=8.42 10^21
