¿Cuántos moles de H2 se pueden formar al reaccionar completamente 6.23 moles de Li con el agua?

you are not a person or not results from a little more of the problem and the more of you can do that in your own way for you are not the only way for a child that you have to do so in your own way of thinking about your own life is not the

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.
