%C= 62.0%
%H2= 10.4%
%O2= 27.5%
To find these, you divide the molar mass of the specific element in the compound divided by the molar mass of the entire compound.

What is the mass percent of chlorine in CCl3F?
77.42% mass of chlorine / mass of entire chemical x 100 = percent composition
What is the percent composition by mass of phosphorous in ammonium phosphate?
149
What is the precent composition of hydrogen in water?
The formula of water is H2O. The gram atomic mass of hydrogen is 1.008 and the gram atomic mass of oxygen is 15.999. Therefore, the mass percent composition of hydrogen in water is 100{(2)(1.008)/[(2)(1.008) + 15.999] or 11.19 %.The percent composition of hydrogen in water is: 11,19 %.
What information is needed to calculate the percent composition of a compound?
The formula of the compound and the Atomic Mass of its elements.
What mineral accounts for 35 percent of the Earth's composition?
No *mineral* accounts for that much of Earth's composition, though the *element* iron makes up 32-35% of the mass of Earth
Percent composition is expressed as a percent by?
Percent composition is usually expressed as a percent by mass, but in the case of gases and vapors, it is often expressed as a percent by volume.
What the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
What is the mass percent of chlorine in CCl3F?
