Which statement about mesosaurus fossils and continental drift is most accurate?
the mesosaurus could have evolved on both continents, so the fossils are not evidence for
continental drift.
the mesosaurus fossils are found over too large of an area to provide any information
about continental drift.
the mesosaurus lived in coastal areas so the fossils show that the coastlines have changed
as the continents drifted apart.
the mesosaurus could not swim between the continents in the open ocean, so the fossils
show that the continents must have been together in the past.

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.
