When 2 grams of hydrogen (h2) react with 32 grams of oxygen (o2) the reaction yields hydrogen peroxide (h2o2) how many grams of ho202 are produced in this reaction

as per the reaction we have

so here 1 mole of H2 react with 1 mole of O2 and give 1 mole of H2O2 as the product

now we will find the moles of given reactant

moles of H2

moles of O2

so here both present in 1 mole each hence the product will also formed 1 mole

so here we have

H2O2 will form

so mass of the product

mass = moles* molecular mass

so the product mass will be 34 g
