PLZ HELP AND HURRY WILL MARK BRAINLIST IF U SHOW WORK When enough energy is present, water will decompose into hydrogen and oxygen gases according to the following reaction:

2 H2O → 2H2 + O2

What mass of water, in grams, must react to produce 25 g of O2?
The molar mass of water is 18.01 g/mol
The molar mass of oxygen is 32.00 g/mol

Show all steps in the solution of this question, including proper units, for full credit !!

not clear

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
