The balanced reaction equation for combustion of heptane, C7H16, is

C7H16+11O2⟶7CO2+8H2O

If the reaction produced 34.5 g CO2,
how many grams of heptane were burned?

Respuesta :

Answer: m = 11.2 g C7H16

Explanation: First convert the mass of CO2 to moles. Then do the mole ratio between CO2 and C7H16 which is 7:1. Finally convert the moles of C7H16 to the mass of C7H16.
