Question

Cuantos moles son 110g de HCl?
(Planteado)

Answer 1

1. calcular Mm HCl

H. 1 x 1 = 1 g/mol
Cl: 1 x 35.45 = 35.45 g/mol
```````````````````````````````````````
       Mm = 36.45 g/mol

2. calcular moles

n = 110 g HCl  x  1 mol HCl
                           ``````````````
                           36.45 g HCl

n = 3.017 moles HCl

otra forma: n= masa/Mm

n = 110 g / 36.45 g/mol

n = 3.017 moles HCl
