How does 100 mL of hydrogen and 50 mL of oxygen give 100 mL of water?

The Gay Lussac’s Law of Gaseous Volumes said that when gases combine or are produced in a chemical reaction they do so in a simple ratio by volume provided all gases are at same temperature and pressure. Thus, 100 mL of hydrogen combine with 50 mL of oxygen to give 100 mL of water vapour.

How much water is hydrogen and oxygen?

Water consists of one oxygen atom and two hydrogen atoms. This means that the mass of a water molecule is 1g + 1g + 16g = 18 g/ mol. When the number of moles of water is known, one can calculate how many grams of weight this is, by using the molar weight of water.

How much hydrogen is in a Litre of water?

In one liter of water, there is about 111.11 gr Hydrogen with the volume of 1.33 m3, and 888.8 gr of Oxygen and it’s volume is 0.670 m3!

How much oxygen is in a Litre of water?

what is the amount of oxygen in i litre of water? can anyone pls give me the ans? Water has 1 part of oxygen. That means 18 g of water is present in 22.4 L. This has 8 g of oxygen.

How many grams of hydrogen are in water?

An amount of any substance in grams that is numerically equal to its atomic or molecular weight in amu has been defined as one mole of that substance. By this definition, one mole of hydrogen is 2.016 grams, one mole of methane is 16.043 grams, and one mole of water is 18.015 grams.

How much hydrogen is in a gram of water?

hydrogen is 2/18ths of the atomic mass of H2O. 2/18th of 36 is 4, so the answer is 4 grams.

How much hydrogen and oxygen is in a cup of water?

I know that water is 2 parts hydrogen and 1 part oxygen. Hydrogen and oxygen are quite light gasses, they don’t weigh very much compared to water.

How many hydrogen atoms are in 100g water?

100g of water is 5.56 moles of water which would have 11.12 moles of H atoms. 5 g of an unknown substance even if it was pure hydrogen could only be 5 moles of H atoms. 20 g of hydrogen gas is 10 moles of H2 which is 20 moles of H atoms.

How many grams of hydrogen are in 200 grams of water?

Because the atomic mass of hydrogen is approximately 1 and oxygen is 8. There are two atoms of hydrogen for every single oxygen atoms in a molecule so there is a 2:8 or 1:4 ratio of mass. So for 200 grams of water, divide by 4 to get the number of grams of hydrogen.

How many oxygen atoms are there in 18 grams of water?

And, since the chemical formula for water is H 2O, 1 mole of water corresponds to 1 mole of oxygen atoms. Therefore, there will be 6.022 × 1023 oxygen atoms in 1 mole, or 18 g of water.

What is the mass and volume of oxygen and hydrogen required?

The mass of oxygen required is 102.7 moles * 32g/mol = 3286.4 grams. The volumes required (uncompressed) can be derived from the approximation of 22.4L/mol for ideal gases. The volume of hydrogen required is 205.4 moles * 22.4L/mol = 4601L. The volume of oxygen required is 102.7 moles * 22.4L/mol = 2300L.

How many moles of oxygen are in 36 grams of water?

Now, 36 grams of water equals two moles of water from the equation: Thus according to the molar ratio, we should have half the amount of moles, that is one mole of diatmoic oxygen. 1 Oxygen atom has a mass of 16 grams, thus diatomic oxygen weights twice as much- 32 grams.
