24. a solution has a very high hydroxide ion concentration. based on this, what would you predict about this solution? (2 points)
it has a very high hydrogen ion concentration.
it has a very low ph.
it will have a very slippery feeling.
it will form salt and water when added to a base.

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

will have a gram-molecular weight of 352g.
