An element crystallizes in a structure having fcc unit cell of edge 300 pm. Calculate its density if 180 g of this element contain `3.708xx10^(24)` atoms.

Density of a unit cell is respresented as rho = (" Effective no. of atoms (s)" xx "Mass of a unit cell ")/("Volume of a unit cell ")=(Z.M)/(N_(A).a^(3)) where , mass of unit cell =mass of effectuive no . of atoms(s) or ion (s). M= At . mass// formula N_(A) = Avogadro' s no . rArr 6.0323 xx 10^(23) a= edge lemght of unit cell An element crystallizes in a structure having fcc unit cell of an edge 200 pm . Calculate the density , if 100 g of this element contains 12xx10^(23) atoms :
