Can the atomic mass of a molecule be found if the chemical formula is known?

Well first of all a molecule doesn't have an Atomic Mass it has a molecular mass.
It's molecular mass is found by adding up the atomic masses of all the elements that make up the molecule. These atomic masses are found on a Periodic Table.
For example water has a formula of H20.
This means it is made of 2 hydrogen atoms and 1 oxygen atom.
Hydrogen has an atomic mass of 1 g/mol while oxygen has an atomic mass of 16 g/mol.
So the molecular mass of water is 2 x 1g/mol + 1 x 16 g/mol = 18 g/mol

What tells you how many atoms are in a single molecule of the compound?
Multiply each element by the subscript for that element for each element in a molecule. When there is no subscript, it is understood to be 1. H2O: 2 x H, 1 x O = 3 atoms CO2: 1 x C, 2 x O = 3 atoms C2H6: 2 x C, 6 x H = 8 atoms
What is a set of symbols that tells how many of each type of atoms are found in a molecule?
This is a chemical formula.
A chemical formula shows kind and number of atoms that form a?
It is not a formula, it is the atomic number and the mass number.The atomic number is the number of protons.The mass number is the weight of a single atom of the element and also the number of protons and neutrons.The number of neutrons can be found by taking the proton number from the atomic number.If you are talking about moles and titration then change the question and I will give a more suitable answer.
Who found the styrene molecule?
The chemical formula is C6H5CH=CH2; it is clear, the molecule contain carbon and hydrogen. Exelus Inc. claims to have first made styrene.
How is the chemical formula for hydrogen found?
Hydrogen is an element, with the symbol of H. Hydrogen gas is usually found as a diatomic molecule- 2 atoms of hydrogen linked to each other, having a formula of H2
What is meant by term chemical formula?
A chemical formula is the "name" of the molecule of the substance. For example Water's chemical formula is H2O, it represent how many atoms of each element are involved. There are 2 hydrogen and 1 oxygen in the above example.

How you calculate atomic mass unit?
Step 1: Write out the chemical formula of the compound whose atomic mass you want to calculate. The chemical formula provides the number of atoms in one molecule of a compound (i.e. the chemical formula for water is H2O). For example, the chemical formula of phosphate is H3O4P.Step 2: Look up the atomic mass for each individual element in the given compound on the periodic table. This number is commonly found just below the letter symbol for the element. For our example, the atomic mass of hydrogen (H) is 1.008 amu per atom, oxygen (O) is 16.00 amu per atom and phosphorous (P) is 30.97 amu per atom.Step 3: Multiply the result for every atom in Step 2 by the number of atoms in one molecule of the compound. Phosphate contains three atoms of hydrogen, four atoms of oxygen and one atom of phosphorous in one molecule. So for phosphate the calculations would be as follows; 1.008 amu/atom x 3 hydrogen atoms per molecule = 3.024 amu of hydrogen per molecule, 16.00 amu/atom x 4 oxygen atoms per molecule = 64.00 amu of oxygen per molecule and 30.97 amu/atom x 1 phosphorous atom per molecule = 30.97 amu of phosphorous per molecule.Step 4: Add the numbers calculated for each atom in Step 3 together to determine the total amu for one molecule of the compound. So for phosphate the atomic mass is 3.024 + 64.00 + 30.97 = 97.99 amu in one molecule of phosphate.
