This question is about stoichiometry, which is a section of chemistry that involves calculating the quantities of reactants and products in a chemical reaction. The balanced chemical equation given is:
From this equation, we can see that 1 mole of ethylene (C2H4) produces 2 moles of carbon dioxide (CO2). The molar mass of C2H4 is approximately 28.05 g/mol, and the molar mass of CO2 is approximately 44.01 g/mol. So, if we start with 45 grams of C2H4, we first need to convert this to moles by dividing by the molar mass of C2H4:
Since 1 mole of C2H4 produces 2 moles of CO2, 1.61 moles of C2H4 will produce 2 * 1.61 = 3.22 moles of CO2.Finally, we convert this back to grams by multiplying by the molar mass of CO2:
So, 45 grams of C2H4 will produce 141.43 grams of CO2.
