Question

Show how to set up the following: How many grams of H2O will be produced by the combustion of 32.8 grams of C2H6? (Remember to balance the equation first)

Answer 1

Answer: 64.0 grams of H2O will be produced.

Step-by-step explanation:

The balanced equation for the combustion of C2H6 is 2C2H6 + 7O2 → 4CO2 + 6H2O. This means that for every 1 mole of C2H6, 6 moles of H2O will be produced. Since 32.8 grams of C2H6 is equal to 1 mole, 6 moles of H2O will be produced, which is equal to 64.0 grams of H2O.
