Chemsitry AS question

What mass of oxygen is produced when 136g of hydrogen peroxide molecules decompose?

Please could you show step by step how you get your answer,thanks...

Reply 1

nota bene

H2O2 => H2 + O2

136g H2O2, what is that in moles?

since molar ratio is 1:1 just multiply the number of moles of H2O2 by the relative atomic mass oxygen gas.
