75 mL of water is measured in a graduated cylinder. The mass of the water should be A.
more than 75 grams
B.
less than 75 grams
C.
there is no good way to tell
D.
75 grams

D-75 grams

Explanation:

that is the answer

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.
