The answer to that question is as follows. I want to know the solution process.

3. The Seebeck coefficient for pure LaCoo, is +600 VK-!. (a) What are the mobile charge carriers? (b) Suppose these occur because the crystal contains a trace of an impurity, Cott, calculate the defect concentration and the formula of the material (data from Robert et al., 2006). 3. (a) Holes; (b) concentration, 0.00095: LaCo03.00095
