8. What is the mass relationship between washers and grams?​

You should have a collection of metal washers, a beaker, and some water. The average mass of each washer is 16.5 grams.

answer; i believe that the correct answer is (a); a large rock being weathered by wind and rain;

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.
