Problem- Serum taken from a patient being treated with lithium for lithium concentration. A reading of 341 units was obtained 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, and this spiked serum gave an intensity reading of 867 units. What is the original concentration of Li in the serum?
