The total mass is 222.6 + 77.4 = 300.0 g. The percent of nitrogen is therefore:
100(222.6/300.00) = 74.2 %. By difference, the percent of oxygen is 25.8 %.
Can you be more specific? Percent composition is usually the percent of an element in a compound.
Percent Composition
Percent composition is a calculation of how much of the molecular weight of a compound is due to a particular element within that compound. For Al(CN)3, the percent composition of aluminum would be 27 / (27 +[12 x 3] + [14 x 3]) = 25.7%
CaS
The formula of the compound and the Atomic Mass of its elements.
71.5 %
60.2/84.2 x 100% = 71.5%
Can you be more specific? Percent composition is usually the percent of an element in a compound.
20.0g Ca + 16.0g S = 36.0g CaS % Composition of Ca = 20.0g Ca/36.0g CaS x 100 = 55.6% Ca

Percent Composition
The percent composition of a compound tells the amount of each element in the compound as a percentage. It is possible to find if the mass of an element and the total mass of the compound is known.
This is the percent chemical composition.
Percent composition is a calculation of how much of the molecular weight of a compound is due to a particular element within that compound. For Al(CN)3, the percent composition of aluminum would be 27 / (27 +[12 x 3] + [14 x 3]) = 25.7%
The molecular formula of the compound can be calculated from the composition of element in a compound. The next steps are involved in the calculation of percentage of every element in a compound.
