26.65 gm of compound having formula [Cr(H_2O)_5Cl)]Cl_2.H_2Ois mixed with 498.2gm water. If complex is 75% ionised in water, then find elevation in boiling point in Kelvin for abovesolution (k_b​ water = 0.50 k kg mol^(-1)) (At. wt. Cr : 52, Cl : 35.5, O : 16)

Answer»


SOLUTION :`26.65/266.5`=0.1 MOLE
TOTAL WATER =498.2+18=500 GM
`DeltaT_b=im k_b=(1+2xx3/4)0.1/0.5xx0.5`
=0.25
