A battery contains two metals that have different tendencies to attract electrons. If one is litium with an electron affinity of -3.05, and the other is zinc with an electron affinity of -0.76, describe how the electrons will flow. Then, describe how you could make this an even stronger battery.

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.
