A solution of Iron (III) chloride is reacted with an aqueous solution of sodium carbonate. 35.0 ml of a 0.17M solution of the iron (Ill) chloride is placed in a beaker. Calculate the volume of a 0.25M solution
of sodium carbonate that is required to react exactly (stoichiometric amount) with the iron solution.

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.
