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.
No; water is made up of water molecules. Water molecules contain two hydrogen molecules and one oxygen molecule.
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.
Yep. That is true.
None. A water molecules contains one oxygen atom and two hydrogen atoms. Oxygen only contains oxygen.
Hydrogen bonds are what holds water molecules together. They are made up of two Hydrogen atoms and one Oxygen atom. The electromagnetivity of the Oxygen atoms help make this possible.
No. Water is not an element it consists of molecules made from hydrogen and oxygen
No; water is made up of water molecules. Water molecules contain two hydrogen molecules and one oxygen molecule.
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.
No, water is a molecule; it is comprised of hydrogen and oxygen atoms.
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
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.
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.
No, Water is a molecule with hydrogen and oxygen
It comes from the splitting of water molecules.
Water is made of two Hydrogen atoms and one oxygen atom. Usually chemicals are made of molecules so (atoms < molecules < chemicals).
Water, H2O, is made of molecules. These water molecules are made of atoms. 2 Hydrogen atoms and 1 Oxygen atom.
No. Water vapor is water in a gaseous state. It consists of water molecules each with one oxygen atom and two hydrogen atom.
