Q:

In a face centred cubic lattice, atom A occupies the corner positions and atom B occupies the face centre positions. If one atom of B is missing from one of the face centred points, the formula of the compound is

1) $A_{2} B_{5}$

2) $A_{3} B_{2}$

3) $A_{2} B_{3}$

4) $A_{3} B_{4}$

A) Option 1	B) Option 2
C) Option 3	D) Option 4

Answer & Explanation Answer: A) Option 1

Explanation:

$Z_{A} = \frac{8}{8}$ ; $Z_{B} = \frac{5}{2}$

So formula of compound is $A B_{\frac{5}{2}}$

i.e., $A_{2} B_{5}$ .

Q:

Ethylene glycol is used as an antifreeze in a cold climate. Mass of ethylene glycol which should be added to 4 kg of water to prevent it from freezing at –6°C will be: (Kf for water = 1.86 Kg/mol and molar mass of ethylene glycol = 62 kg/mol)

A) 204.60 g	B) 304.30 g
C) 804.32 g	D) 400.00 g

Answer & Explanation Answer: C) 804.32 g

Explanation:

$∆ T_{f} = k_{f} . m$

for ethylene glycol in aq. solution

$∆ T_{f} = k_{f} \frac{w}{m o l . w t} \times \frac{1000}{w t . o f s o l v e n t} 6 = \frac{1.86 x w x 1000}{62 x 4000}$

=> w = 800 g

So, the weight of solute should be more than 800 g.
