Question

how many grams of water are produced from 100 grams of oxygen

Answer 1

Answer:

If we decompose 100 grams of pure water by passing electricity through it then 11 grams of hydrogen and 89 grams of oxygen obtained. This experiment shows that water always consists of the same two elements hydrogen and oxygen combine together in the same constant proportion of 11: 89 or 1:8 by mass.

Answer 2

Answer:

U think the question should be how many grams of oxygen and hydrogen are produced if water is 100 grams.

The ans for that is:

2H2O -> O2 + 2H2

Or… 1 mol of water produces 1 mol of hydrogen and 1/2 mol of oxygen

each mol of water is 18.016 g per mol

100 g = 100/18.016 or 5.55062 moles of water

Each mol of hydrogen is 2.016 g

so it requires 2.016*100/18.016 or 11.19 g of hydrogen

oxygen required is 0.5*100/18.016 moles or 2.77531 moles

molar mass of oxygen is 32 g

so 2.7753 x 32 mol = 88.81 g of oxygen

together 88.81 g oxygen and 11.19 g hydrogen gets you back to 100 g of water…

Hope this helps if not l am really sorry.
