Respuesta:
m = 320 g de CH3OH
Explicación:
2CH3OH + 3O2 → 2CO2 + 4H2O
Datos:
m CO2 = 440 mg / 1000 = 0.440 g
m CH3OH = ¿?
Mm CO2 = 44 g/mol
Mm CH3OH = 32 g/mol
1. Calcular masa de CH3OH
m = 0.440 g CO2 x 1 mol CO2 x 2 mol CH3OH x _32 g CH3OH_
44 g CO2 2 mol CO2 1 mol CH3OH
m = 0.32 g de CH3OH
2. Calculkar la masa en mg
m = 0.32 x 1000
