Suppose 9.5 g of gaseous C2H2 reacts with excess O2 according to the reaction below. What is the mass of CO2 produced? C2H2(g) + O2(g) → CO2(g) + H2O(ℓ)
Firstly we need to correct the equation - it isn't balanced as you wrote it. For the complete combustion of ethyne|
So, the stoichiometry tells us that 1 mole of ethyne makes 2 moles of carbon dioxide.
Moles of ethyne = mass of ethyne /
