Problem 95P

PROBLEM 95P

The ingestion of lead from food, water, or other environmental sources can cause lead poisoning, a serious condition that affects the central nervous system, causing symptoms such as distractibility, lethargy, and loss of motor function. Lead poisoning is treated with chelating agents, substances that bind to lead and allow it to be eliminated in the urine. A modern chelating agent used for this purpose is succimer (C4H6O4S2). Suppose you are trying to determine the appropriate dose for succimer treatment of lead poisoning. Assume that a patient's blood lead levels are 0.550 mg/L, that total blood volume is 5.0 L, and that 1 mol of succimer binds 1 mol of lead. What minimum mass of succimer in milligrams is needed to bind all of the lead in this patient's bloodstream?

Step-by-Step Solution:
Step 1 of 3

Solution 95P

Let blood be called B. Let succimer be called S.

Atomic weights: Pb=207, C=12, H=1, O=16, S=32, C4H6O4S2=182

5.0LB x 10 d'LB/1 LB x 26 ugPb/1dLB x 1gPb/(1x10^6 ugPb) x 1mol Pb/207gPb x 1 molE/1 molS x 182 gS/1 molS x 1000mgS/1gS = 1.14 mg succimer.
