Molecular Formula Drill
Dr E. Ramanathan PhD The molecular formula of a compound represents the exact number and type of atoms present in a molecule of the compound. It is derived from the empirical formula by determining the actual number of atoms of each element in the molecule, based on its molar mass. Here is a list of…

Determination of atomic mass
Atomic mass can be determined by applying the following formula. Atomic mass = (w1A1 + w2A2)/(w1+w2) If the weight is given in terms of weight percentage replace w1 as w1% , w2 as w2 % and (w1 + w2) as 100 respectively in the above equation.
