A mixture (X) contains two liquids with large difference in their boiling points. Another mixture (Y) contains two liquids with not much difference in their boiling points. Mixtures X and Y can be separated respectively by the methods
The number of unit cells in 5.85 g of cube shaped ideal crystal of NaCl \((Z=4)\) is \(x\times10^{21}\). The value of x is
The crystal structure of an element has fcc lattice. If the edge length of the crystal is \(4\ \text{\AA}\), what is the atomic weight \((g\ mol^{-1})\) of the element, if the density of the crystal is \(11.21\ g\ cm^{-3}\)? \[ (N_A=6.023\times10^{23}\ mol^{-1}) \]
The density of Na is 0.613 g cm\(^{-3}\). If the edge length of the unit cell of Na is 5 Å, the effective number of atoms of Na per unit cell is (Atomic weight of Na = 23 u):
Ag crystallizes in fcc lattice. What is the total number of tetrahedral voids present in \(540 \, \text{g}\) of Ag metal? \((N_A=\text{Avogadro number}; \text{Ag atomic weight}=108 \, \text{g mol}^{-1})\)
The ratio of effective number of atoms in a unit cell of FCC and BCC lattices is:
