Equivalent weight of element X is 3. If vapour density of volatile chloride of X is 77, Find out the moleculer formula of chloride.

Explanation

Equivalent weight of chloride of X= Equivalent weight of Cl +equivalent weight of X = 35.5+3=38.5
Moleculer weight of chloride = vapour density `xx2=77xx2=154`
`"Valency of the element" X=(154)/(38.5)=4`
Chlorine is taken as monovalent, since it is chloride
Molecular formula of chloride of X is `XCl_(4)`
