SATHEE: Some Basic Principles Of Organic Chemistry Question 136

Some Basic Principles Of Organic Chemistry Question 136

Question: $116 m g$ of a compound on vaporization in a Victor Meyer’s apparatus displaces $44.8, m l$ of air measured at S.T.P. The molecular weight of the compounds is [Kerala PMT 2004]

Options:

A) 116

B) 232

C) 58

D) 44.8

E) 46.4

Show Answer

Answer:

Correct Answer: C

Solution:

$116, m g$ compounds means $116 \times 10^{- 3} g m$ compound since $1 m g$ contain $10^{- 3} g m$ Mol.

wt. of compound $= \frac{mass of the substance}{volume of the vapour at S .T .P .} \times 22400$

$= \frac{116 \times 10^{- 3}}{44.8} \times 22400$ =57.99% or 58.0%
