Answer 1

Answer:

hi there

Explanation:

Answer 2

Given: If limiting molar conductivity of Ca* and Cl are 119.0 and 76.3 S cm mol".

To find: The value of limiting molar conductivity of CaCl.

solution: from Kohlrausch's law,

AcaCh = Ac +2Ac

AceC 119 + 2 x 76.3

119+152.6

271.6 cm mol

The limiting molar conductivity of CaCl, is 271.6 cm mol

Therefore option (b) is correct choice.
