Chemical formula for water is H2O. One water molecule has 2 hydrogen atoms. That means 10 hydrogen atoms are needed to form five water molecules.
The ration between hydrogen and oxygen in a water molecule is 2:1. In five water molecules, there are five oxygen atoms. According the ratio, there are 10 hydrogen atoms.
What else can I help you with?
How many molecules of hydrogen in water?
There are two atoms of hydrogen in a water molecule, but no hydrogen molecules.
How many hydrogen atoms in 80 water molecules?
In 80 water molecules, there are a total of 160 hydrogen atoms. Each water molecule contains 2 hydrogen atoms. Multiplying the number of water molecules by the number of hydrogen atoms in each gives the total.
How many hydrogen atoms are in 6H2O?
There are 12 hydrogen atoms in 6 molecules of water (H2O). Each water molecule contains 2 hydrogen atoms, so multiplying by the number of water molecules gives a total of 12 hydrogen atoms.
How are elements atoms and molecules are related?
Atoms are elements , e.g Hydrogen. Molecules are combinations of atoms, e.g water H2O is the combination of Hydrogen and Qxygen.
What determines the cohesiveness of water molecules?
The cohesiveness of water molecules is determined by hydrogen bonds. These bonds form between the hydrogen atoms of one water molecule and the oxygen atoms of neighboring water molecules, creating a strong attraction that allows water molecules to stick together.
What is the number of hydrogen molecules in water?
In a water molecule (H2O), there are two hydrogen atoms.
How many hydrogen molecules 2H2O?
There are a total of 4 hydrogen atoms in 2 molecules of H2O. Each water molecule has 2 hydrogen atoms.
How many atoms are needed to make 30000000000000000000 molecules of water?
To make 30,000,000,000,000,000,000 (3 x 10^19) molecules of water, you would need 180,000,000,000,000,000,000 (1.8 x 10^20) hydrogen atoms and 90,000,000,000,000,000,000 (9 x 10^19) oxygen atoms, as each water molecule consists of 2 hydrogen atoms and 1 oxygen atom.
Why does having 2 hydrogen molecules make water instead of peroxide?
Water is H2O and hydrogen peroxide is H2O2 ; both of these molecules have two hydrogen atoms. It is the number of oxygen atoms which varies.
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
Each water molecule contains two hydrogen atoms. Therefore, the number of water molecules present in the sample can be calculated by dividing the number of hydrogen atoms by 2. In this case, 3.6 moles of hydrogen atoms corresponds to 1.8 moles of water molecules. This is equal to approximately 1.08 x 10^24 water molecules.
What makes water molecules cluster together?
Water molecules cluster together due to hydrogen bonding, which occurs between the slightly positive hydrogen atoms and the slightly negative oxygen atoms of neighboring water molecules. These hydrogen bonds create a network of interconnected water molecules, leading to the formation of clusters.
How many molecules are present in a molecule of hydrogen?
there are 2 atoms of hydrogen in water
