2 C8H18 + 25 O2 →16 CO2 + 18 H2O
Mm C8H18 = 114 g/mol
CO2 = 32 g/mol
1. convertir millas a Km
1 milla ---- 1.609 Kkm
125 millas ---- x
x = 201.13 Km
2. Calcular Km/L
Km/L = (19.5 millas/ 1 galón) x (1 galón/3.785 L) x (1.609 Km / 1 milla)
Km/L = 8.28
3. Calcular volumen de gasolina
litros = 201.13 Km x (1 L / 8.28 Km)
Litros gasolina = 24.29
4. calcular masa de gasolina utilizando la densidad
masa = 24.29 L x ( 1000 mL / 1 L) x ( 0.69 g / 1 mL)
masa = 16760 g de C8H18
5. calcula gramos de CO2
g CO2 = 16760 g C8H18 x 1 mol C8H18 x 16 mol CO2 x 44 g CO2
``````````````````````` ``````````````````````` `````````````````````
114 g C8H18 2 mol C8H18 1 mol CO2
g CO2 = 51750
6. convertir g a Kg
Kg = 51750 / 1000 = 51.750
