[Jawaban] Pentane, C5H12, will react as shown below: C5H12(l) + O2 → CO2 + ____H2O 1. Balance the equation above by putting coefficients into each blank space. - Answer: 1C5H12 + 8O2 → 5CO2 + 6H2O 2. How many atoms of oxygen are in 144 grams of pentane? Step 1: 144 g of C5H12 × (1 mole / 72.17 g) = 1.995 moles of C5H12 Step 2: 1.995 moles of C5H12 × (8 moles of O2 / 1 mole of C5H12) = 15.962 moles of O2 Step 3: 15.962 moles of O2 × (6.02 × 10^23 atoms of O2 / 1 mole of O2) = 9.609 × 10^24 atoms of O2 3. How many atoms of oxygen are in 192 grams of carbon dioxide gas? Step 1: 192 grams of CO2 × (1 mole of CO2 / 44.01 grams of CO2) = 4.363 moles of CO2 Step 2: 4.363 moles of CO2 × (2 atoms of O / 1 mole of CO2) = 8.726 moles of O atoms Step 3: 8.726 moles of O atoms × (6.02 × 10^23 atoms / 1 mole) = 5.253 × 10^24 atoms of O 4. A) CIRCLE ONE: True or False: The reactant you begin with fewer grams of is your limiting reactant. B) If 32 g of oxygen gas and 32 g of pentane are combined, how much water will be produced, in moles? (Use your reaction from the top of the first page) Note: Review the calculations for accuracy and ensure the steps align with stoichiometric principles.
