6. Galvanized iron is steel sheet that has been coated with zinc; "tin" cans are made of steel sheet coated with tin. Discuss the functions of these coatings and the electrochemistry of
the corrosion reactions that occur if an electrolyte contacts the scratched surface of a
galvanized iron sheet or a tin can.​

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

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

will have a gram-molecular weight of 352g.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
