# 116mg of a compound on vaporization in Victor mayer's apparatus displaces 44.8ml of air measured at STP.The molecular mass of the compound is

$(a)\;116\qquad(b)\;232\qquad(c)\;58\qquad(d)\;46.4$

As we know that 1g mole of any gas occupies 23.4l as 22400ml of volume at STP or NTP
Molar mass of compound =mass of 22400 ml vapour at STP
$\Rightarrow \large\frac{0.116\times 22400}{44.8}$$=58$
Hence (c) is the correct answer.
