(A) The molecular weight of the metal chloride $(MCl_3)$ is given by $2 	imes 	ext{vapour density} = 2 	imes 81.25 = 162.5$.Let the equivalent weight of the metal be $E$.The molecular weight of $MCl_3$ is $M + 3 	imes 35.5 = 162.5$,where $M$ is the atomic weight of the metal.Since the metal is trivalent,its atomic weight $M = 3 	imes E$.Substituting this into the equation: $3E + 106.5 = 162.5$.$3E = 162.5 - 106.5 = 56$.$E = \frac{56}{3} = 18.66$.

What will be the equivalent weight of a metal if the vapour density of the chloride salt of a trivalent metal is $81.25$?
