# How do you find the ratio of hydrogen and oxygen in water?

## How do you find the ratio of hydrogen and oxygen in water?

(i) 11.1⋅g/1.00794⋅g⋅mol−1=11.02⋅mol with respect to hydrogen. (ii) 88.9⋅g/16.00⋅g⋅mol−1=5.56⋅mol with respect to oxygen. The ratio of hydrogen to oxygen in water is 1:8 by mass.

Why is the ratio of hydrogen to oxygen 2 1?

Because Water’s chemical representation is H₂O. That means, each water molecule has 2 hydrogen atoms & 1 oxygen atom. When electricity passes through water, the H₂O molecule breaks up into 2 Hydrogen & 1 oxygen atoms. So their ratio is 2 : 1.

### What is the hydrogen to oxygen mass ratio in hydrogen peroxide and water 1 16?

1: 16
Hydrogen and oxygen are combined in the ratio 1: 16 by mass in hydrogen peroxide.

What is the best ratio of hydrogen to oxygen?

Theoretically, a ratio of 2:1 hydrogen:oxygen is enough to achieve maximum efficiency; in practice a ratio 4:1 or 5:1 is needed to avoid an oxidizing flame.

#### What is the percentage of oxygen in hydrogen peroxide?

The calculation for oxygen is really similar. Again, there’s two oxygens in the compound. So, there would be 31.998 grams per mole of oxygen in hydrogen peroxide. We divide that by the total mass of the compound, multiply it by 100%, and get the mass percent of oxygen in hydrogen peroxide being about 94%.

What is the ratio of the mass of oxygen in the hydrogen peroxide?

## How many hydrogen and oxygen atoms are in a water molecule H2O?

two hydrogen
A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom.

Is it OK to mix hydrogen and oxygen?

Simply mixing hydrogen and oxygen together won’t make water. Hydrogen and oxygen both exist as diatomic gases. A reaction between them requires energy to break the bonds between the atoms so they can form a new product.

### What happens if you mix hydrogen with oxygen?

When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide.
