State what is the original concentration of li in the serum

Reference no: EM13192843

Serum taken from a patient being treated with lithium for manic-depressive illness was analyzed for lithium concentration. A reading of 296 units was obtained for the intensity of the 671 nm red emission line. Then 1.00 mL of a 10.9 mM Lithium standard was added to 9.00 mL of serum, and this spiked serum gave an intensity reading of 721 units. What is the original concentration of Li in the serum?
