Na2CO3 + Ca(OH)2 → 2NaOH + CaCO3
Mm Na2CO3 = 105.98 g/mol
NaOH = 39.99 g/mol
Ca(OH)2 = 74 g/mol
1. convertir Kg a g
g = 5 x 1000 = 5000 g
2. calcular gramos de NaOH
g NaOH = 5000 g Na2CO3 x 1 mol Na2CO3 x 2 mol NaOH x 39.99 g NaOH

105.98 g Na2CO3 mol Na2CO3 1 mol NaOH
g = 3773.35 de NaOH
3. Convertir g a Kg
Kg = 3773.35 / 1000 = 3.77335 Kg de NaOH
