What discovery led Darwin to develop his theories on adaptation? a.

b.
The Galapagos islands originate from volcanoes.
c.
The birds Darwin found in the Galapagos were different types of finches, not separate types of birds.
d.
Many of the organisms in the Galapagos lived in hostile environments

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.
