How are the chemical properties of natural different from synthetic wood?

The series of chemical reactions that are used to change natural resources into synthetic products is called chemical synthesis. To make a "natural" product, the natural resource is not chemically changed as much. ... It is more natural than synthetic, because its shape has been changed, but the material is still wood.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
