Answer to Question #48174 in Chemistry for lisa
Question #48174
the normal lead content in human blood is about 0.40 part per million. a value of .80 part per million is considered to be dangerous. how many grams of lead are contained in 6.0 *10 to the 3rd power of blood if the lead content is 0.62part per million?
Expert's answer
The lead content is 0.62/10^6. We can calculate howmany grams of lead are contained in 6.0*10^3 of blood (0.006*10^6) by
multiplying (0.006*10^6)*(0.62/10^6) = 0.00372g of lead.
multiplying (0.006*10^6)*(0.62/10^6) = 0.00372g of lead.
