The disinfectant hydrogen peroxide (h2o2) decomposes to form water and oxygen gas. how much o2 will result from the decomposi- tion of 7.24 mol of hydrogen peroxide? answer in units of mol.

3.62 moles

Explanation:

The decomposition reaction of hydrogen peroxide is shown below as:

Given that :

Moles of hydrogen peroxide = 7.24 moles

From the reaction,  

2 moles of hydrogen peroxide on reaction forms 1 mole of oxygen gas

Also,

1 mole of hydrogen peroxide on reaction forms 1/2 mole of oxygen gas

So,

7.24 moles of hydrogen peroxide on reaction forms mole of oxygen gas

Moles of oxygen gas formed = 3.62 moles

i think its 5049.

i hope this !
