Dilute aqueous hydrogen peroxide is used as a bleachingagent and for disinfecting surfaces and small cuts. Its concentra-tion is sometimes given as a certain number of “volumes hydro-gen peroxide,” which refers to the number of volumes of O₂ gas,measured at STP, that a given volume of hydrogen peroxide so-lution will release when it decomposes to O₂ and liquid H₂O.How many grams of hydrogen peroxide are in 0.100 L of “20volumes hydrogen peroxide” solution?

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
