I'll assume that the lung volume is 5.30 L. 1L= 1dm 3 5.30dm 3 x ( 1m/ 10 dm )3 x ( 1.5 ug pb / m 3) x ( 1 g pb /1 x 10 6 ug pb ) x ( 1 mole pb /207.2 g pb) x( 6.02 x 10 23 pb atoms / 1 mole pb) =2.3 x 10 13 pb atoms
Hereditary Diseases are passed on from one generation to another through defective genes. These diseases are transmitted in the same family. The chromosomes in the humans are responsible for passing the traits from the parent to the offspring.
Hope this help
