Ответ:
There will be produced 44.8 moles of CO2
Explanation:
Step 1: Data given
Number of C5H12 = 8.96 moles
O2 is in excess, this means C5H12 is the limiting reactant
Molar mass of C5H12 = 72.15 g/mol
Molar mass of O2 = 32 g/mol
Step 2: The balanced equation
C₅H₁₂ + 8 O₂ ⟶ 6 H₂O + 5 CO₂
This means for 1 mol C5H12 we need 8 moles of O2 to produce 6 moles H2O and 5 moles CO2
Step 3: Calculate moles of CO2
Since C5H12 is the limiting reactant.
For 1 mol C5H12 we need 8 moles of O2 to produce 6 moles H2O and 5 moles CO2
For 8.96 moles C5H12 we'll have 5*8.96 = 44.8 moles
There will be produced 44.8 moles of CO2
