To find the mass of an atom you divide the constant known as Avagadro's number
6.022X10^23 by the amu of an element. So lets take oxygen for example. The amu of Oxygen is " 15.99" , so you would divide 15.99 by 6.022X10^23. By doing this you will get the mass of one Oxygen atom.

What is the mass of a single molecule of water?
- calculate the molecular mass of the substance from the atomic weights of the contained elements - 1 molecule gram of any substance contain 6,023 141 79.1023 molecules (Avogadro number) - mass of a single molecule is: Molecular mass in grams/Avogadro number
Why the mass of hydrogen molecule is greater then the mass of hydrogen atom?
The hydrogen molecule, H2, contains two hydrogen atoms and thus, has twice the mass of a single hydrogen atom.
How can you find the mass of any compound?
The molar mass of a compound is the sum of atomic weights of elements in the molecule.
What is a group of symbols that show the kind and number of each element in a single unit of a molecule called?
Mass
What the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
What would be the unit to use to measure a single molecule?
the term gram molecule was used in chemistry and this unit is used to measure a single molecule in gram molecule.
What is the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
How do you find the atomic mass of C7H8?
You mean molecular mass or moler mass, not atomic mass! Add up the atomic masses of all the atoms in the molecule.
How do you find the percentage of calcium in calcuim bicarbonate molecule?
Mass percent = Mass of part / Total Mass * 100% Atomic mass of calcium = 40 Molecular mass of calcium bicarbonate = 162 40 / 162 *100 = 24.7% Calcium by weight in a Calcium Bicarbonate Molecule.
What is a molar mass of a molecule?
The molar mass of a molecule is the sum of atomic weights of the elements contained in this molecule.
