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?
