Question

2. Distinguish between a. Formula mass and molecular mass of a compound b. Empirical and molecular formula AMALAN L

​

Answer 1

Thus, the main difference is that- Formula mass is calculated by simply adding the masses of atoms present in the simplest formula. But, the Molecular mass is calculated using the actual numbers of atoms present in a molecule. The empirical formula of a compound gives the simplest ratio of the number of different atoms present, whereas the molecular formula gives the actual number of each different atom present in a molecule
