Question

What is the formula for finding out formula mass??

Answer 1

Dear student, To calculate the formula mass of a compound you not only need to know its formula, but you must also be able to interpret the symbols, numbers, and brackets in the formula. The formula mass is calculated by adding up all the atomic masses for every atom in the formula. The unit for formula mass is either u or Da (Daltons). The amu has been replaced with u, even though it is still commonly used. Regards
