Question

Answer the following question based on the previously determined balanced chemical equation (H2O2--> 2H2O + O2)

for the decomposition of hydrogen peroxide. Express your answer to two decimal places.

How many grams of H₂O₂ are needed to make 39.94 moles of O₂ ?

Answer 1

Using the balanced equation we can solve the problem as follows:

(34.02 g H₂O₂/1 mole H₂O₂) (1 mole O₂/1 mole H₂O) (39.94 mol O₂) = answer (do the math & you got it.
