1.5 ug/m^3 = 0.0015 ug/L.
0.0015 ug/L x 5.50 L = ? micrograms Pb in the lungs. Convert to grams.
Then mols Pb = g Pb/atomic mass Pb
The
maxlevel that the EPA considers safe for lead in air is 1.5 microgram/m3
. If your lungs were filled
with air containing this level of lead, how many moles of lead atoms would be in your lungs? (Assume a
total lung volume of 5.50 L and 1 cm3 = 1mL.)
