Question

Solid balls of radius 17.32 cm crystallises in bec pattern, during one such crystallisation some oxygen gas is trapped. This trapped oxygen at 640K creates pressure of 5 atm Assume:(i) BCC arrangement is not disturbed due to trapping of gas.(ii) Gas is uniformly distributed inside unit cell\lbrack Take R 0.08 atm-litre/mole-K, N_a =6 x 10^{23}, Mass of a solid ball =64g. 1) Calculate number of oxygen molecules present in a unit cell 2) Calculate percentage increase in density due to trapping of ga
