Equivalent weight of X is 9. The vapour density of chloride salt is 66

1.	Equivalent weight of X is 9. The vapour density of chloride salt is 66.75 state vulency of X.
Answer» Solution :MOLECULAR MASS `= 2 xx"VAPOURS DENSITY"` `=2xx 66.75 = 133.50` `:. "Valency"=("Molecular mass")/("Equivalent weight")` `=(133.50)/(9+35.5) = (133.50)/(44.5)=3`
