Question

in a reaction between sodium sulfate and iron(III) acetate how many grams of sodium acetate will be formed from 8.26 * 10 to the 25 molecules of iron(III) acetate? does anyone know how to do this??

Answer 1

First you need a balanced equation

3Na2SO4 + 2Fe(C2H3O2)3 == 6NaC2H3O2 + Fe2(SO4)3

Now convert the molecules of Iron(III) Acetate to moles using Avogdro's number.

Now multiply by the molar ratio of 6/2. That gives you moles of Na Acetate.

Now multiply by the molar mass and you are done.
