Calculati volumul de dioxid de carbon(c.n) obtinut prin arderea a 125 cm3 etanol (p=0,78 g/ml) ρ = m/V

Calculati volumul de dioxid de carbon(c.n) obtinut prin arderea a 125 cm³ etanol (p=0,78 g/ml)

ρ = m/V

m solutie = ρ ∙ V=0.78*125=97.5 g

Ecuatia reactiei este:

97.5g………………………….x l
CH₃ – CH₂ – OH + 7/2 O₂ → 2CO₂ + 3H₂O

46g…………………………..2*22.4l

.x=94.95 l
