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.
Water is 18 grams to the mole, so 5.3 moles of water is 95.4 grams. Hydrogen makes up 11% by mass of water, and 11% of 95.4 is 10.5 grams of hydrogen. That's about 10.5 moles of hydrogen, which at STP would be 235.2 liters.

Or we could go at it this way:
The formula for water is H2O. At least that's what my chemistry teacher told me when he wasn't making surfboards.
To make one mole of water you need one mole of H2 molecules and half a mole of O2 molecules. (Or two moles of hydrogen atoms and one of oxygen atoms, but the hydrogen and oxygen you get from your local welding store is always H2 and O2...so a mole of hydrogen molecules and half a mole of oxygen molecules.)
To make 5.3 moles of water you'll need 5.3 moles of hydrogen molecules, or 10.6 moles of hydrogen atoms. Since a mole of hydrogen atoms weighs one gram (one mole of hydrogen molecules weighs two grams), you will need 10.6 grams of hydrogen to make this much water.
how many grams of hydrogen peroxide are needed to produce 5.0 moles of water? how many grams of hydrogen peroxide are needed to produce 5.0 moles of water?
you need 10. moles of hydrogen to make 5 moles of water, although hydrogen is diatomic so you need only 5 moles of hydrogen gas the equation looks like this 2H2 + O2 = 2H2O
how many grams of water could be made from 5 mol H2 and 3 mol O2

The answer depends on how big the bottle is and what material it is made of.
5 grams of water in a teaspoon
Depends upon the density of the liquid. For water there would be 6000 grams in 6l of water. For alcohol, it could less than 5000grams. Litre is a fluid measure, grams are a massmeasure.
5 grams of water in a teaspoon
5 grams.
180 grams of water is 10 moles of water.
7 grams of water is 7 ml
54,0 grams of water is equivalent to 3 moles.
For water (this only applies to water): grams = milliliters.
380 grams of water is 1.676 cups380 grams of water is 1.676 cups
If it is water, it is 275 grams.
