Question

te por reaccion del cloruro de sodio con el acido sulfurico ¿cuantas moles y gramls del HCL pueden prodixirse a partir de 375 y acido sulfurico

Answer 1

              2NaCl + H2SO4 → Na2SO4 + 2HCl

Mm H2SO4 = 98 g/mol
             HCl = 36.45 g/mol

1. calcular moles de HCl

moles HCl = 375 g H2SO4 x  1 mol H2SO4  x    2 mol HCl 
                                               ``````````````````      `````````````````
                                                 98 g H2SO4     1 mol H2SO4

moles HCl = 7.653

2. calcular gramos de HCl

g HCl = 375 g H2SO4 x  1 mol H2SO4  x    2 mol HCl    x  36.45 g HCl
                                        ``````````````````      `````````````````    ````````````````
                                         98 g H2SO4       1 mol H2SO4    1 mol HCl

g HCl = 278.95
