What is the difference between molecular mass and formula mass?

In case of ionic compounds we have crystal lattice composed of ions. And there is a never ending pattern of ions and that made it difficult to calculate the molecular mass. Thus we used a simple method by taking the ratio of the ions and then adding their masses, like in case of NaCl ;

What is the difference between stereoisomers, optical isomers and enantiomers?

Stereoisomers :- These are the compounds that have same molecular formula but different arrangement of atoms in the space. Optical isomers :- The compunds that have same molecular formula but they rotate the plane polarised light to the different side, right side-dextrorotatory and left levorotatory. Enantiomer :- These are the compounds that are mirror images
