A partir de la siguiente ecuacion equilibrada obtener la masa de O2 H2O y CO2 sabiendoque contamos con 156gr de etano
Respuestas
2C2H6 + 7 O2 → 4 CO2 + 6H2O
Mm C2H6 = 30 g/mol
O2 = 32 g/mol
CO2 = 44 g/mol
a calcular gramos de O2
g O2 = 156 g C2H6 x 1 mol C2H6 x 7 mol O2 x 32 g O2

30 g C2H6 2 mol C2H6 1 mol O2
g O2 = 582.4
b. calcular gramos de agua
g H2O = 156 g C2H6 x 1 mol C2H6 x 6 mol H2O x 18 g H2O

30 g C2H6 2 mol C2H6 1 mol H2O
g H2O = 280.8
g calcular gramos de CO2
g CO2 = 156 g C2H6 x 1 mol C2H6 x 4 mol CO2 x 44 g CO2
