Question

write the formula for determination of molecular weight​

Answer 1

Answer:

calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7 neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons.

Answer 2

Answer:

molecular weight = (number of carbon atoms)(C atomic weight) + (number of H atoms)(H atomic weight) so we calculate as follows: molecular weight = (6 x 12.01) + (14 x 1.01).
