Questions & Step-by-Step Solutions

How many grams of CO2 are produced from the complete combustion of 1 mole of C3H8?
  • Step 1: Write the balanced chemical equation for the combustion of propane (C3H8). The equation is C3H8 + 5O2 → 3CO2 + 4H2O.
  • Step 2: Identify how many moles of CO2 are produced from 1 mole of C3H8. From the equation, 1 mole of C3H8 produces 3 moles of CO2.
  • Step 3: Calculate the mass of CO2 produced. Each mole of CO2 has a mass of 44 grams.
  • Step 4: Multiply the number of moles of CO2 by the mass of one mole of CO2. So, 3 moles of CO2 * 44 grams/mole = 132 grams of CO2.
  • Stoichiometry – Understanding the mole ratios in chemical reactions to calculate the amount of products formed from a given reactant.
  • Molar Mass Calculation – Calculating the mass of a substance using its molar mass and the number of moles produced.
