∙ 12y ago2 Hydrogen atoms and 1 Oxygen atom= water molecule
Wiki User
∙ 13y ago4 moles of oxygen atoms (being present in 4 moles of H2O)
and, so:
4 moles of oxygen atoms is 4*6.02*1023 = 24.1*1023 molecules ATOMS of oxygen
Wiki User
∙ 13y agoOne molecule of water is H20 which has only 1 Oxygen, Therefore 4 molecules of water have 4 atoms of oxygen in four molecules of water
Wiki User
∙ 11y agoThere are 4 oxygen atoms in 4 molecules of water.
Wiki User
∙ 7y agoOf course, four moles of water.
Wiki User
∙ 6y agoTwo moles of oxygen are necessary.

How many grams of hydrogen are needed to produce 30.0 grams of water?
The synthesis reaction is 2 H2 + O2 = 2 H2O. Every two moles of hydrogen reacts with one mole of oxygen to make two moles of water. Then 30.0 grams of water is 1.67 moles, and 1.67 moles of H2 has a mass of 3.37 grams. 25.0 grams of O2 is .781 moles, so 1.562 moles of H2 are needed, or 3.15 grams.
How many total moles of KNO3 must be dissolved in water to make 1.5 liters of a 2.0 M current?
8 moles of KCl are needed.
How many grams of water could be made from 5.0 mol H2 and 3.0 mol O2?
The formula for Oxygen gas is O2, and the formula for water is H2O. Each molecule of Oxygen gas can produce 2 molecules of water (with enough Hydrogen, of course). So, 2.5 moles of Oxygen gas would be required to produce 5.0 moles of water.
How many moles of hydrogen will it take to make 36 grams of water?
Answer: 16 g of oxygen and 2 g of hydrogen.
When 10 moles of H2 are mixed with 10 moles of O2 what is the number of moles of water formed?
Write out the equation first: 10H2 + 10O2 --> xH2O Since there are 2 moles of Hydrogen for every mole of Oxygen and equal moles of both are given, the Hydrogen limits the reaction as the limiting reactant. 10 moles of Hydrogen can make 10 moles of H2O with 5 moles of Oxygen left over. Think of it logically: H2 is two hydrogen atoms and water needs two hydrogen atoms, so it is a one-to-one reaction.

If you combine four atoms of oxygen gas and two atoms of hydrogen gas how many atoms of water and oxygen gas will be produced?
I was wondering about this... but I think if you combined..The four oxygen gas O2, and the two of Hydrogen gas H2.. and predict was will happened I guess this is what it will or might be calculate, but Im not sure.KKKO2O2+H2H1O4+H2O2H
HOW MANY MOLES OF O2 ARE NEEDED TO MAKE 3 MOLE OF WATER?
3 moles of O, so that must be 6 moles of O2
How many liters of water are needed to react with 2L of oxygen to make water?
Water does not need to react with oxygen to make water!
Does 10o2 plus 10H2 make 20 moles of water?
No, this would make 5 moles. This is because water is H2O. This means that for each oxygen molecule used, there will be 2 hydrogen molecules used. In the given equation Only 5 moles of oxygen could be used to pair with all 10 moles of hydrogen, therefore giving you an excess of 5 oxygen molecules.
How do you figure out how much water you make when you ignite oxygen and hydrogen?
The amount of water formed from a reactionof hydrogen and oxygen conforms to the chemical equation: 2H2 + O2 --> 2H2O For every two moles of hydrogen which reacts with one mole of oxygen, 2 moles of water are formed.
Why does it not rain on the moon?
There is no atmosphere on the moon and no water.
