Question

how to calculate molecular mass
tell with example please ​

Answer 1

Answer:

1) Determine the molecular formula of the molecule.

2) Use the periodic table to determine the atomic mass of each element in the molecule.

3) Multiply each element's atomic mass by the number of atoms of that element in the molecule. This number is represented by the subscript next to the element symbol in the molecular formula.

4) Add these values together for each different atom in the molecule.

The total will be the molecular mass of the compound.

Example of Simple Molecular Mass Calculation

For example, to find the molecular mass of NH3, the first step is to look up the atomic masses of nitrogen (N) and hydrogen (H).

H = 1.00794

N = 14.0067  

Next, multiply the atomic mass of each atom by the number of atoms in the compound. There is one nitrogen atom (no subscript is given for one atom). There are three hydrogen atoms, as indicated by the subscript.  

molecular mass = (1 x 14.0067) + (3 x 1.00794)

molecular mass = 14.0067 + 3.02382

molecular mass = 17.0305
