Question

Quizplus · Accepted Answer

To determine the molecular formula, we need to know the molar mass of hydrogen peroxide. Knowing properties or density only gives us information about its physical characteristics, while the number of moles in a given mass only tells us about its stoichiometry or molar mass based on Avogadro's constant. The molar mass of hydrogen peroxide can be determined by adding the atomic masses of all the atoms in the molecule, which would give us a molar mass of 34.01 g/mol. This is an important piece of information to determine the molecular formula based on empirical formula and molar mass.
