Moles NaHCO₃necesarios = (0.35 moles CH₃COOH)( 1 mol NaHCO₃/1 mol
CH₃COOH) = 0.35 moles NaHCO₃
Moles CH₃COOH necesarios = (0 moles NaHCO₃)(1 mol CH₃COOH/ 1 mol NaHCO₃)
= 0 moles CH₃COOH
moles CH₃COOH en exceso: 0.35 moles CH₃COOH - 0 moles CH₃COOH = 0.35
moles CH₃COOH
Moles CH₃COO-Na = (0 moles NaHCO₃)(1 mol CH₃COO-Na/ 1 mol NaHCO₃) = 0
moles CH₃COO-Na
Moles H₂O = (0 moles NaHCO₃)(1 mol H₂O/ 1 mol NaHCO₃) = 0 moles H₂O
Moles CO₂ = (0 moles NaHCO₃)(1 mol CO₂/ 1 mol NaHCO₃) = 0 moles CO₂
Gramos CH₃COO-Na = (0 moles CH₃COO-Na)(36 gr CH₃COO-Na/ 1 mol
CH₃COO-Na) = 0 gr CH₃COO-Na
Moles H₂O = (0 molesH₂O)(18 gr H₂O/ 1 mol H₂O) = 0 gr H₂O
Moles CO₂ = (0 moles CO₂)(44 gr CO₂/ 1 mol CO₂) = 0 gr CO₂
Rendimiento teórico: 84 gr NaHCO₃ → 44 gr CO₂
0 gr NaHCO₃ → x
x = 0 gr CO₂ al 100%
Rendimiento de la reacción: (0 gr CO₂)(1840 gr CO₂/100%) = 0 %
Pasar gr a moles:
1mol NaHCO₃ → 84 gr
x → 5 gr
x= 0.059 moles NaHCO₃
84 gr/mol 60 gr/mol
NaHCO₃ + CH₃COOH → CH₃COO-Na + H₂O + CO₂
5 gr 20 ml = 21 gr
