1 Answer
It means that the atoms in a particular structure are repeated in the molecule.
Explanation:
An example,
The atomic weights of the components:
- Ca - calcium - 40.078
- P - phosphorus - 30.973762
- O - oxygen - 15.9994
(3 x 40.078) + ((30.973762 + (4 x 15.9994)) x 2)
120.234 + ((30.973762 + 63.9976) x 2)
120.234 + (94.971362 x 2)
120.234 + 189.942724
310.177
So the answer is 310.177 g/mol
