44. The concentrations of lead in blood samples are often reported in units of micromoles of lead per liter of blood. Calculate the value of the concentration in these units of a blood sample containing 45 ppb lead, assuming that the density of blood is one gram per milliliter.© BrainMass Inc. brainmass.com October 9, 2019, 4:07 pm ad1c9bdddf
A mole is an amount of a substance that contains 6.023*10^23 molecules or atoms. A micromole is one-millionth of a mole.
thus, 1 micro mole = 6.023*10^17 atoms
Owing to the dilute nature of the ...
