Question

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

Answer 1

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

= 0.116×22400/44.8=58

C is your answer

Hope it will help you
