Eg) Silicon Material

When we say about mobility of a semiconductor - we basically have to consider its properties etc. One of it is impurities. Here we have to consider its TOTAL Dopant Concentration?

No, you don't consider the TOTAL dopant concentration if what you mean by that is

Concentration x VOLUME = Total number of DOPANTS.

The reason doping is quantified in terms of a CONCENTRATION is that you know the number of dopants, say, in a 1 nm^3 cube where transport becomes relevant.

Maybe this answers your question?
