Question

How many moles of oxygen gas are necessary to completely react with 10.6 moles of propane? C3H8(g) + 5 O2(g) --> 3 CO2 (g) + 4 H2O (l)

Answer 1

Answer:

53 moles of oxygen, O₂

Explanation:

The chemical equation for the reaction is presented as follows;

C₃H₈(g) + 5O₂(g) → 3CO₂(g) + 4H₂O (i)

From the above equation, 5 moles of oxygen, O₂, gas reacts completely with 1 mole of propane gas, C₃H₈

Therefore 10.6 × 5 = 53 moles of oxygen, O₂, will be required to react with 10.6 × 1 mole of propane, C₃H₈

The number of moles of oxygen, O₂, necessary to completely react with 10.6 moles of propane, C₃H₈ is 53 moles of oxygen, O₂
