Vapour density of a compound is defined as the ratio of mass of a certain volume of gas to the mass of the same volume of hydrogen gas under conditions of temperature and pressure. Vapour density=("Mass of certain of gas"(22.4L)"atSTP")/("Mass of same volume of" H_(2) "gas"(22.4L)"at STP") =(Mw)/(2) i.e., Molecular mass of gas=Vapour density xx2 Vapour density is a unitless quantity it is unaffected by variation of temperature and pressure. Vapour density of a metal chloride is 66. its oxide contains 53% metal. the atomic mass of the metal is:

1.	Vapour density of a compound is defined as the ratio of mass of a certain volume of gas to the mass of the same volume of hydrogen gas under conditions of temperature and pressure. Vapour density=("Mass of certain of gas"(22.4L)"atSTP")/("Mass of same volume of" H_(2) "gas"(22.4L)"at STP") =(Mw)/(2) i.e., Molecular mass of gas=Vapour density xx2 Vapour density is a unitless quantity it is unaffected by variation of temperature and pressure. Vapour density of a metal chloride is 66. its oxide contains 53% metal. the atomic mass of the metal is:
Answer» 21 54 27.06 2.086 Solution :Number of equivalents=Number of equivalents `(53)/(E)=(47)/(8)` E=9.02 Atomic mass of metal=`nxx9.02` Molecular formula of metal chloride `=MCl_(n)` Molecular mass `=[nxx9.02+nxx35.5]=132` ltbr. N=3 `THEREFORE` Atomic mass of metal`=3xx9.02=27.06`
