If 14.3 moles of h2o2 is decomposed, how many grams of oxygen gas are produced?

The balanced chemical reaction would be as follows:

2H2O2 = 2H2O + O2

We are given the amount of the peroxide that decomposes. Using this as the starting point for the calculations, we can determine the amount of O2 produced. We do as follows:

14.3 mol H2O2 ( 1 mol O2 / 2 mol H2O2 ) = 7.15 mol O2 produced

Hello there.

If 14.3 moles of H2O2 is decomposed, how many grams of oxygen gas are produced?

7.15 mol O2 produced

Ithink it's carbonic acid
