116 mg of a compound on vaporisation in a victor Meyer's apparatus displaces 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)g` compound.
since 1 mg contain `10^(-3)` g
Mol. Wt. of compound `= ("mass of the substance")/("Volume of the vapour at STP") xx 22400`
`= (116 xx 10^(-3))/44.8 xx 22400 = 58`
