In the formula #H_2O_2 -> H_2O + O_2#, how many grams of #O_2# are produced from the decomposition of 68 g of #H_2O_2#?
Your equation is not correctly balanced. The correct equation is as follows:
First, calculate the moles of
Next, we must compare the moles of hydrogen peroxide and oxygen gas. According to the corrected equation, this mole ratio is as shown below:
Thus, the moles of oxygen produced in this reaction will be exactly half the moles of hydrogen peroxide reacting.
Finally, convert from moles into mass, given that
