26.65 gm of compound having formula [Cr(...

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

Text Solution

Verified by Experts

The correct Answer is:
B

`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
