The lithium concentration in serum taken from a patient being treated with lithium for manic-depressive illness was analyzedusing flame emission spectroscopy. A sample of the serum gave a reading of 313 units for the intensity of the 671 nm redemission line. Then, 1.00 mL of a 10.7 mM lithium standard was added to 9.00 mL of serum. This spiked serum gave anintensity reading of 775 units at the 671 nm emission line. What is the original concentration of Li* in the serum?[Li*] =mM

Concentration is the measure of how much of a given substance is mixed with another substance.
