atomic weight

IIT JEE 2015 Sample Questions › Physical Chemistry questions › atomic weight

An element X forms iodide XI₃ and chloride XCl₃.The iodide is quantitavely converted to the chloride when heated in stream of chlorine.
2XI₃+3Cl₂---->2XCl₃+3I₂.If 0.5 g of XI₃ is treated ,0.2360g XCL3 obtaine.CAlculate atomic weight of element X

moles of XI3=moles of XCl3

0.5/(3M1+M)=0.236/(3M2+M)

M1 = atomic weight of Iodine
M2 = atomic weight of Chlorine
