`116 mg` of a compound on vaporisation in a Victor `-` Meyer's apparatus displaced `44.8 mL` of air measured at `S.T.P.` The molecular mass of the compound is

A

116

B

232

C

58

D

44.8

Text Solution

Verified by Experts

The correct Answer is:
c
`116 mg `compounds means `116 xx 10^(-3) gm` compound since `1 mg ` contain `10^(-3)gm`
Mol. Wt. of compound `=("mass of the su bstance")/("volume of the vapour of S.T.P.")xx22400`
`=(116xx10^(-3))/(44.8)xx22400=57.99%` or `58.0%`
