Question

20% of compound-A in benzene has same boiling point as 45% of compound-B in same solvent. If molar mass of A is 20 g fat ¹(hen molar mass of B is (compound-A is non-electrolyte but compound-B undergoes 100% dimerization at the given concentration)​

Answer 1

Answer:

Distance covered with 1 step = 1 m

Time taken = 1 s

Time taken to move first 5 m forward = 5 s

Time taken to move 3 m backward = 3 s

Net distance covered = 5 – 3 = 2 m

Net time taken to cover 2 m = 8 s

Drunkard covers 2 m in 8 s.

Drunkard covered 4 m in 16 s.

Drunkard covered 6 m in 24 s.

Drunkard covered 8 m in 32 s.

In the next 5 s, the drunkard will cover a distance of 5 m and a total distance of 13 m and falls into the pit.

Net time taken by the drunkard to cover 13 m = 32 + 5 = 37 s
