If 507 g FeCl2 were used up in the reaction FeCl2 + 2NaOH Fe(OH)2(s) + 2NaCl, how many grams of NaCl would be made?

Question

If 507 g FeCl2 were used up in the reaction FeCl2 + 2NaOH  Fe(OH)2(s) + 2NaCl, how many grams of NaCl would be made?

DrBob222 · Answer

Write the equation and balance it.
Convert 507 g FeCl2 to mols. mols = grams/molar mass.
Using the coefficients in the balanced equation convert mols FeCl2 to mols NaCl.
Now convert mols NaCl to g. g = mols x molar mass.
