Finding mass in stoichiometry
WebStoichiometry (/ ˌ s t ɔɪ k i ˈ ɒ m ɪ t r i /) is the relationship between the quantities of reactants and products before, during, and following chemical reactions.. Stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the total mass of the products, leading to the insight that the relations among quantities … WebWe can tackle this stoichiometry problem using the following steps: Step 1: Convert known reactant mass to moles In order to relate the amounts \ce {H2SO4} HX 2SOX 4 and \ce {NaOH} NaOH using a mole ratio, we first need to know the quantity of \ce {H2SO4} HX …

So if we have 0.139 mols of glucose, we will have 0.833 mols of oxygen (0.139 x 6 = 0.834, but accounting for sig figs it becomes 0.833). Hope that helps. Comment ( 8 votes) Upvote Downvote Flag more
