The lithium concentration in serum taken from a patient being treated with lithium for manic-depressive illness was analyzed using flame emission spectroscopy. A sample of the serum gave a reading of 274 units for the intensity of the 671 nm red emission line. Then, 1.00 mL of a 11.5 mM lithium standard was added to 9.00 mL of serum. This spiked serum gave an intensity reading of 609 units at the 671 nm emission line. What is the original concentration of Li* in the serum? mM [Li*] =

The lithium concentration in serum taken from a patient using flame emission spectroscopy. A sample of the serum gave a reading of 178 units for the intensity of the 671 nm red emission line. Then, 1.00 mL of a 11.8 mM lithium standard was added to 9.00 mL of serum. This spiked serum gave an intensity reading of 5.30×102 units at the 671 nm emission line. What is the original concentration of Li+ in the serum?
