The mass of water that decomposes to produce 4 grams of hydrogen gas and 32 grams of oxygen gas is 36 grams. This is because the molar ratio of hydrogen to oxygen in water is 2:1, so for every 2 grams of hydrogen produced, 16 grams of oxygen are produced. Thus, to produce 4 grams of hydrogen and 32 grams of oxygen, a total of 36 grams of water must have decomposed.
The percentage of oxygen is 54,84 %.
800 g oxygen are needed.
When hydrogen reacts with oxygen to form water, the ratio is 2:1. This means that for every 2 grams of hydrogen, 1 gram of water is produced. Therefore, if 300 grams of hydrogen react with unlimited oxygen, 150 grams of water will be produced.
Also 10 grams.

When 2.5 moles of oxygen react with hydrogen, they react in a 1:2 ratio to produce water. Therefore, 2.5 moles of oxygen will produce 5 moles of water. To convert moles to grams, you'll need to know the molar mass of water, which is approximately 18 grams/mol. So, 2.5 moles of oxygen will produce 90 grams (5 moles x 18 grams/mole) of water.
The percentage of oxygen is 54,84 %.
The proportion by mass of hydrogen to oxygen in hydrogen peroxide is 1:16. This means that for every 1 gram of hydrogen in hydrogen peroxide, there are 16 grams of oxygen.
Petrol contains about 84% carbon and 16% hydrogen by weight so a litre weighing 700 grams contains 588 grams of carbon and 112 grams of hydrogen. In the engine it would burn with 2464 grams of oxygen to produce 2156 grams of CO2 and 1008 grams of water (steam), which is normally invisible but can be seen in the exhaust gases from a cold engine.
The balanced chemical equation for the reaction of hydrogen and oxygen to form water is 2H2 + O2 -> 2H2O. Based on the equation, for every 2 grams of hydrogen, 64 grams of oxygen are needed to form 36 grams of water. Thus, if 8 grams of hydrogen react completely with 64 grams of oxygen, the total mass of water formed would be 36 grams.
It is not measured in grams but PPM because it is a gas.
800 g oxygen are needed.

43.2 grams of water
45 g water are obtained.
Well, honey, when 6.00 grams of hydrogen get cozy with 40.00 grams of oxygen, they throw a little party and make 46.00 grams of water. It's like a chemical love story, but with more H2O and less drama. So, grab your umbrella because it's raining water!
