The ppm concentration of Pb2+ in a blood sample were measured with Spectrophotometry. 5.00 mL of a blood sample were taken and this sample gave a signal of 0.301 a.u.. Another 5.00 mL of a blood sample were mixed with 0.50 mL og 1.75 ppm Pb2+. Then, this mixture was diluted to 25.00 mL and this diluted mixture gave a signal of 0.406 a.u.. What is the ppm concentration of a blood sample?

What is the ppm concentration of a blood sample?
Expert Solution
Step 1
To find out the concentration of in a blood sample given that the 5.00 mL sample of a blood sample give a signal at 0.301 a.u while when a 5.00 mL blood sample of was mixed with 0.50 mL of 1.75 ppm solution and then diluted to 25.00 mL gave a peak at 0.406 a.u.
