Question

2HCl + NaCO3 --- 2NaCl + H2CO3
cuantos moles de HCl se requieren para producir 200 gr de NaCl

Answer 1

                            2HCl + H2SO4 → 2NaCl + H2CO3

Mm NaCl = 58.45 g/mol

calcular moles HCl

n HCl  = 200 g NaCl x  1 mol NaCl  x  2 mol HCl
                                    ````````````````    ````````````````
                                    58.45 g NaCl   2 mol NaCl

n HCl = 3.422  moles HCl
