Consider the reaction of aluminum chloride with silver acetate. how many milliliters of 0.250 m alcl3 would be needed to react completely with 20 ml of 0.500 m agc2h3o2 solution? the net ionic equation for the reaction is: ag + cl -> agcl

answer: c.

explanation:

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.
