🤓 Based on our data, we think this question is relevant for Professor Foster's class at GMU.
From the given data, at STP, it was said “20 volumes of hydrogen peroxide” were involved which also means “20 volumes of O2”
Balanced equation will appear as
2 H2O2 (aq) → O2 (g) + H2 (l)
Therefore 1 L of hydrogen peroxide gives 20 L of O2 or (20 L O2 per 1 L solution)
Dilute aqueous hydrogen peroxide is used as a bleaching agent and for disinfecting surfaces and small cuts. Its concentration is sometimes given as a certain number of “volumes hydrogen peroxide,” which refers to the number of volumes of O2 gas, measured at STP, that a given volume of hydrogen peroxide solution will release when it decomposes to O2 and liquid H2O. How many grams of hydrogen peroxide are in 0.100 L of “20 volumes hydrogen peroxide” solution?
