The elevation of boiling point of0.10maqueousCrCl3.xNH3solution is two times that of0.05 maqueousCaCl2solution. The value ofxis..
[Assume100%ionisation of the complex andCaCl2,coordination number ofCras6,and that allNH3molecules are present inside the coordination sphere]

Answer:
5.00
Solution:

0.05m aqueous CaCl2 =0.15molal solution of non electrolyte

Since the elevation in boiling point is double so the molality of given solution of complex =0.3m

Hence the complex must be producing three ions in the solution, so its formula =CrNH35ClCl2

SO X=5
