Textbook Problem

If blood contains 50. ppb lead, how many atoms of lead are there in 1.0 L of blood? (Assume d(blood) = 1.0 g/mL.)

Interpretation Introduction

Interpretation:

The number of atoms of lead in 1.0 L of blood should be calculated.

Concept introduction:

Lead belongs to group 4A of the periodic table. Lead and its compounds are considered poisonous and can cause lead poisoning in individuals. Some of the common symptoms of lead poisoning are pain in abdomen, nausea, and headache. Lead poisoning is more common in infants. The salts of lead are sweet in taste.

Numberofmoles=MassofthesubstanceMolarmass

Numberofatoms=Numberofmoles×Avogadronumber

Explanation

The number of atoms of lead in 1.0 L of blood is calculated below.

Given:

Blood contains 50 ppb of lead which is 50 g of lead in 1×109 g of blood.

The density of blood is 1.0 g/ml.

Thus, 1×103 ml of blood is equal to 1×103 g of blood.

Now,

1×109 g of blood contains 50 g of lead.

1 g of blood contains 50 g1×109 g of lead.

1×103 g of blood contains (50 g1×109 g)(1×103 g) of lead
