According to the following reaction, how many moles of water will be formed upon the complete reaction of 25.6 grams of hydrogen peroxide (H2O2)?

Question

According to the following reaction, how many moles of water will be formed upon the complete reaction of 25.6 grams of hydrogen peroxide (H₂O₂)?

hydrogen peroxide (H₂O₂) (aq) water (l) + oxygen (g)

 moles water

Answer 1

2H₂O₂(aq) ==> 2H₂O(l) + O₂(g) ... balanced equation

molar mass H₂O₂ = 34 g/mol

moles H₂O₂ present = 25.6 g x 1 mol / 34 g = 0.753 mols

moles H₂O produced = 0753 mols H₂O₂ x 2 mol H₂O / 2 mol H₂O₂ = 0.753 mol H₂O produced
