Answer:
Formula weight and molar mass are both calculated by taking the individual atoms' masses in the formula, multiplying them by how many there are in the formula, and then adding the numbers together.
The similarity between calculating formula weight and molar mass is.
Formula weight is simply the summation of all the masses/weight of each atom present in a chemical formula. it also known as the relative atomic mass . while
Molar mass is determined by obtaining a compound sample and dividing it by the number of substance that is present in the sample. i.e. an average mass is taken
Hence we can conclude that the similarity is Individual masses of the substances/atoms present in the chemical formula are considered.
