Question

A 0.0020 m aqueous solution in an ionic
compound Co(NH3)3(NO2)C1 freezes at
-0.00732°C. Number of moles of ions which
1 mol of ionic compound produces on being
dissolved in water will be (K, = +1.86°C/m)
(2009)
1) 1 2 2 3 3 4 4​

Answer 1

Answer:

i=dTf÷kf×m = 0.00732÷1.86×0.002 = 0.000007871....
