Determining the composition of a coordination compound using molar conductivity

[cncbmb]

Homework Statement

The substance CoBr3 dot 4 NH3 dot 2 H2O ha a molar conductivity of 42 kS/m at infinite dilution. Indicate the composition of the coordination sphere.

Homework Equations

I don't know any relevant equations.

The Attempt at a Solution

Where can we read about how molar conductivity can tell us the composition of a coordination sphere? I googled this and have not found a tutorial on how to do this type of question.

I don't recall molar conductivity being mentioned in my high school chemistry class when we did coordination spheres.

There is no direct link, however, think how the molar conductivity depends on the ions present in the solution - types, numbers, charges... Once you can estimate what ions are present, you can conclude how the complex looks.
