Calculate the overall order of this reaction using the table data.
The U. S. Environmental Protection Agency (EPA) sets
limits on healthful levels of air pollutants. The
maximum level that the EPA considers safe for lead air
pollution is 1.5 μg/m³
Part A
If your lungs were filled with air containing this level of lead, how many lead atoms would be in your lungs? (Assume a total lung
volume of 5.40 L.)
ΜΕ ΑΣΦ
= 2.35 1013
?
atoms
! Check your rounding. Your final answer should be rounded to 2 significant figures in the last step.
