Question

Propane is used as a fuel for camp stoves. It undergoes combustion to form carbon dioxide and water.

C3H8 + 5 02- 3 CO2 + 4H2O
How many molecules of dihydrogen monoxide will be produced from 7.328 moles of propane?
How Do i get this answer with steps ?

Answer 1

1.765x10²⁵ molecules

Step-by-step explanation:

• C₃H₈ + 5 O₂ → 3 CO₂ + 4H₂O

First we convert 7.328 moles of propane (C₃H₈) into moles of H₂O, using the stoichiometric coefficients of the balanced reaction:

• 7.328 mol C₃H₈ *
  `(4molH_2O)/(1molC_3H_8)` = 29.312 mol H₂O

Then we convert 29.312 moles of H₂O into molecules, using Avogadro's number:

• 29.312 mol * 6.023x10²³ molecules/mol = 1.765x10²⁵ molecules
