Si en un matraz aforado tengo una solución 8%m/v , Si a partir de ella preparo otra solución que es 4% m/v esta ultima ¿esta mas diluida o mas concentrada?

I'm sorry i do not speak spanish , so i dont understand.

Explanation:

do you know english

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.

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