Which statement correctly describes a feature of the rock cycle? ORocks are preserved through the process.
ORocks change from one type to another.
ODifferent rock groups are not related to one another.
ORocks change from one type to another in a specific order.

Sediment can only form by weathering, erosion, and deposition.

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.
