Reaction C3H8(g) +502(g) --> 3CO2(g) + 4H₂O(g)
A scientist completes the reaction above and ends
up with 186.68g of carbon dioxide. What mass of
propane (C3H8) would need to be reacted to end
up with that much carbon dioxide? (Round any
atomic masses on the periodic table to one
decimal place.)

Respuesta :

Answer

Procedure

Considering the following chemical equation, which is already balanced

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

We assume there is enough oxygen to react with all propane and thus, propane is the limiting reactant

Therefore we use the equation to determine the amount of propane
