Answer:
The sum of individual atoms can be used to find the mass of a molecule.
The mass of hydrogen peroxide, H2O2 would be calculated like this:
H2O2 has 2 hydrogen atoms and 2 oxygen atoms in it.
Therefore the mass is
2 X H = 2 X 1.01 u = 2.02 u
2 X O = 2 X 16.00 u = 32.00 u
34.02u
So one molecule of hydrogen peroxide weighs in at 34.02 u.
The periodic table provides you with individual atomic masses. If you know the number and type of elements in a molecule you can add up the individual masses to find the molecular mass or molecular weight.
Find the molecular mass of calcium phosphate, Ca3(PO4)2
The molecule has 3 calcium atoms, 2 phosphate atoms and 8 O atoms in it. Stop and verify this for yourself. The Ca has a subscript 3 with it. The P has an assumed 1 and the O has a 4. However the PO4 group has a set of brackets around it with a subscript
