Question

For the reaction: 2H2 + O2 → 2H2O, how many grams of water are produced from

6.00 moles of H2?

Answer 1

108 g

Step-by-step explanation:

• 2H₂ + O₂ → 2H₂O

First we convert 6.00 moles of H₂ into moles of H₂O, using the stoichiometric coefficients of the reaction:

• 6.00 mol H₂ *
  `(2molH_2O)/(2molH_2)` = 6.00 mol H₂O

Then we can convert 6.00 moles of H₂O into grams, using the molar mass of water:

• 6.00 mol H₂O * 18 g/mol = 108 g

The answer is 108 grams of water.
