20.0g Ca + 16.0g S = 36.0g CaS
% Composition of Ca = 20.0g Ca/36.0g CaS x 100 = 55.6% Ca
The total mass of the compound is 20.0 + 16.0 = 36.0. The percentage of Ca is the mass of the Ca over the total mass, so it's 20.0/36.0 = 0.556
60.2/84.2 x 100% = 71.5%
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.
One atom of carbon, two of oxygen.
HClO3 (gram-formula mass = 84 g/mol)
71.5 %
60.2/84.2 x 100% = 71.5%
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
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.
because the compound will scoral
so it goes KABOOM
