Question

detrmina los gramos necesarios de Naoh para producir 395g NaCl

Answer 1

                         NaOH + HCl → NaCl + H2O
Mm NaOH = 40 g/mol       NaCl = 58.5 g/mol

g NaOH = 395 g NaCl  x  1 mol NaCl  x  1 mol NaOH  x  40 g NaOH                                        ````````````````    ``````````````````     `````````````````                                          58.5 g NaCl    1 mol NaCl       1 mol NaOH
g NaOH = 270.09
