The formula of water is H2O and that of oxygen molecules is O2.
The fraction by mass of oxygen in water is the Atomic Mass of oxygen divided by the molecular mass of water, which in turn is the sum of the atomic mass of oxygen and twice the atomic mass of hydrogen, or {15.999/[15.999 + 2(1.008)]} = 0.888, to sufficient significant digits to correspond to the problem information of 52.8 grams of water. The mass of oxygen in this amount of water therefore is 0.888 X 52.8 = 46.9 grams.
The molecular mass of oxygen atoms is 2 X 15.999 = 32.0, so that 46.9 grams corresponds to 46.9/32.0 = 1.466 moles of oxygen molecules.
The number of molecules per mole of any substance is Avogadro's number, 6.022 X 1023. The answer to the problem is this number multiplied by the number of moles = 1.466 X 6.022 X 1023 = 8.83 X 1023.
What else can I help you with?
Is water made of separate atoms or made of molecules?
Water is made up of molecules with the formula H2O (two hydrogens attached to an oxygen) Of course the H (hydrogen) and O (oxygen) are atoms.
Are clouds made of molecules of pure oxygen?
No, clouds are made of water that is heated up so it raises. It then condenses and becomes clouds. The cloud the gets tighter and tighter filled and the water gets heavier and heavier and then it falls down as rain.
How many molecules of oxygen is need to make water?
None. A water molecules contains one oxygen atom and two hydrogen atoms. Oxygen only contains oxygen.
Is water made of atoms or molecules?
Waters is made of molecules. Each of those molecules contains 3 atoms.
Oxygen molecules are made of 2 oxygen atoms that are bound together. Ozone molecules which are very different from oxygen molecules are made of 3 oxygen atoms that are bound together.?
Yep. That is true.
Is water an element made up of water and oxygen atoms?
No. Water is not an element it consists of molecules made from hydrogen and oxygen
Is water made of separate atoms or made of molecules?
Water is made up of molecules with the formula H2O (two hydrogens attached to an oxygen) Of course the H (hydrogen) and O (oxygen) are atoms.
Is water vapor made of oxygen?
No. Water vapor is water in a gaseous state. It consists of water molecules each with one oxygen atom and two hydrogen atom.
Is water made out molecules?
No, water is a molecule; it is comprised of hydrogen and oxygen atoms.
What is water made of?
Water is made up from two elements. Hydrogen and Oxygen. There are 2 Hydrogen atoms/molecules and 1 oxygen. The symbol for water is H2O
Are water molecules made up individual water molecules?
no. atoms are the basic blocks. atoms fit together in certain ways to create molecules. Water is made up of two hydrogen molecules and one oxygen molecule.
Does atoms make up ice?
Ice is made of molecules of water. Molecules of water are made of atoms of hydrogen and oxygen. So yes, ice is made of atoms, too.
Are all molecules made from a single atom?
No, Water is a molecule with hydrogen and oxygen
Where does the oxygen made during photosynthesis come from?
It comes from the splitting of water molecules.
What are the chemicals in a water molecule?
Water is made of two Hydrogen atoms and one oxygen atom. Usually chemicals are made of molecules so (atoms < molecules < chemicals).
Is there hydrogen and oxygen in snow and ice?
Yes, snow and ice are made up of water molecules, which consist of hydrogen and oxygen atoms. When water freezes into ice or falls as snow, the molecules arrange themselves into a crystal structure, forming the solid forms we see.
Why is oxygen in the water molecules?
Water is made of two hydrogen atoms and an oxygen atom. The combination of hydrogen and oxygen is needed in order to create a molecule with the properties characteristic of water. Water cannot exist without oxygen.
