How do I write this chemical equation

What mass of hydrogen peroxide (H2O2) must decompose to produce 0.77 g of water?

**Please DO NOT balance the equation. I just want the UNbalanced chemical equation. I already know how to solve it so please dont do that either. If you balance the equation I WILL NOT even look at your answer. So please DO NOT BALANCE THE EQUATION!

H₂O₂ → H₂O + O₂ Is the skeleton equation

LOL. My union contract doesn't allow me to write unbalanced chemical equation .... so don't tell.

H2O2(l) --> H2O(l) + O2(g)

1.45g H2O2 is the answer
H2O2---> H2O + O2 is the unbalanced equation
