Question

Quizplus · Accepted Answer

According to the balanced chemical equation, 2 moles of H₂O₂ will produce 2 moles of H₂O and 1 mole of O₂. To find the mass of water produced, we need to calculate the molar mass of H₂O, which is 18.02 g/mol.

First, we need to find the number of moles of H₂O₂ in 100 g:
100 g H₂O₂ x 1 mol H₂O₂/34.01 g H₂O₂ = 2.94 mol H₂O₂

According to the stoichiometry, 2 moles of H₂O₂ will produce 2 moles of H₂O:
2.94 mol H₂O₂ x (2 mol H₂O/2 mol H₂O₂) = 2.94 mol H₂O

Finally, we can find the mass of water produced:
2.94 mol H₂O x 18.02 g/mol H₂O = 52.9 g H₂O
