Iron is biologically important in the transport of oxygen by red blood cells from the lungs to the various organs of the body. In the blood of an adult human, there are approximately 2.60 * 10¹³ red blood cells with a total of 2.90 g of iron. On the average, how many iron atoms are present in each red blood cell? (molar mass for Fe = 55.85 g)

Question

Quizplus · Accepted Answer

To find the number of iron atoms per red blood cell, first calculate the moles of iron using the given mass (2.90 g) and the molar mass of iron (55.85 g/mol). Then, multiply the moles by Avogadro's number (6.022 x 10^23 atoms/mol) to find the total number of iron atoms. Finally, divide this number by the total number of red blood cells (2.60 x 10^13) to find the average number of iron atoms per red blood cell.
