Suppose you have a piece of clay. you sprinkle uncooked rice on it to represent rocks and soil on a mountain. what will be least likely to cause the process of erosion in this model? ( explain )
a.) placing the clay with rice under running water
b.) placing the clay with rice in the freezer
c.) placing the clay with rice in front of a running fan

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.
