The Correct Option is C
Solution and Explanation
Step 1: Understanding cubic close-packed (ccp) structure.
In the cubic close-packed structure (also known as face-centered cubic or FCC), each sphere is in contact with 12 neighboring spheres. This leads to a coordination number of 12.
Step 2: Conclusion.
The coordination number in a ccp structure is (C) 12.

[2mm] Order of \(\Delta T_b\) is: - 2 moles of liquid A and 3 moles of liquid B are mixed to from an ideal solution. The vapour pressure of ideal solution is 320 mm Hg. When 1 mole of A & 1 mole of B is further added then new vapour pressure of solution is 328.57 mm Hg. Find the vapour pressure of pure A ($P_A^\circ$) & pure B ($P_B^\circ$):
- If pure liquids A and B have vapour pressures of 55 kPa and 15 kPa respectively. If in a solution of A and B, mole fraction of A in vapour is 0.8, then find mole fraction of A in liquid phase.
- If percentage of N$_2$ above a liquid solution is 80% at a total pressure of 10 atm, then find the mole fraction of N$_2$ gas dissolved in solution.
[Given that Henry’s constant for N$_2$ is $7.6 \times 10^7$ mm Hg]
- Given below are two statements:
Statement-I: \( K_H \) is constant with change in concentration of gas till solution is dilute at a given temperature.
Statement-II: According to Henry’s Law, partial pressure of gas in vapor phase is inversely proportional to mole fraction of gas in solution.
