We’re being asked to calculate the moles of H2O, which will be formed from 42.0 g of H2O2. The flow for this problem will be like this:
Mass of H2O2 (molar mass of H2O2)→ Moles of H2O2(mole-to-mole comparison) → Moles of H2O
Given the following reaction:
2H2O2 → 2H2O + O2
How many moles of H2O will be produced from 42.0 g of H 2O2?
_____ moles (round to three significant figures)
