Question

Cuantos gramos de hidroxido de sodio se necesitan para neutralizar 392.32 g de acido sulfurico?

Answer 1

                  2NaOH + H2SO4 → Na2SO4 + 2H2O

Mm NaOH = 40 g/mol
     H2SO4 = 98 g/mol

g NaOH = 392.32 g H2SO4  x  1 mol H2SO4  x  2 mol NaOH   x  40 g NaOH
                                                  ``````````````````     ``````````````````     ````````````````
                                                   98 g H2SO4      1 mol H2SO4    1 mol NaOH

g NaOH = 320.26
