Question

When propane (C3H8) is burned in air (O2), it completely combusts and produces water (H2O) and carbon dioxide (CO2). How many moles of water would be produced if 5 moles of propane were combusted?

Answer 1

Answer:

20 mol

Explanation:

First, balance the chemical reaction

C3H8 + 5O2 --> 4H2O + 3CO2

Using the mole ratio, we can multiply the moles of propane by 4 to find the moles of H2O.

5 × 4= 20

20 mol
