Carbonic acid - H2CO3
Find the atomic masses of each element and multiply it by however many atoms are in the compound, then add them together.
H = 1.007 × 2 = 2.014
C = 12.01
O = 16.00 × 3= 48.00
Molecular mass = 2.014 + 12.01 + 48.00 = 62.02 grams/mole
Take the mass of a specific element (above) and divide it by the total molecular mass. Change the final answer to a percent
Hydrogen: 2.014 ÷ 62.02 = .0325 = 3.25%
Carbon: 12.01 ÷ 62.02 = .194 = 19.4%
Oxygen: 48.00 ÷ 62.02 = .774 = 77.4%
Carbonic acid contains 3.25% Hydrogen, 19.4% Carbon, and 77.4% Oxygen.
Well, CO2 means 1 Carbon molecules and 2 Oxygen molecules.
This means the overall for Carbon is a third (1/3).
The percentage of this can be best shown as 33.333 reccuring.
In more detail, the atomic weight of carbon is 12 and of oxygen 16. So an atom of CO2 has an atomic weight of 12 + 2x16, that is 44, of which 12 is carbon. So CO2 contains 12/44 of carbon, that is 27% carbon.
Carbonic acid - H2CO3
Find the atomic masses of each element and multiply it by however many atoms are in the compound, then add them together.
H = 1.007
CO is the chemical formula for carbon monoxide. The percent composition of CO is 42.88 percent carbon by mass and 57.12 percent oxygen.
well, in the terms of percent, carbon dioxide has two carbon atoms and one oxygen atom, so the ratio of carbon to oxygen in percent will be %66.66, or 66 2/3%
The chemical formula for carbonic acid is H2CO3.
- hydrogen: 3,25 %
- carbon: 19,35 %
- oxygen: 77,40 %
in atmosphere it is 0.03%
33% carbon, 66% Oxygen

The percent composition of manganese dichoride (MnCl2) is: - Mn: 44 % - Cl: 56 %
The percent composition for CuBr2 is: Cu= 28.45% Br= 71.55%
One atom of carbon, two of oxygen.
your face it it co2
The percent composition of lithium in LiOH is: 29,21 %.
Can you be more specific? Percent composition is usually the percent of an element in a compound.
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.
The percent composition of ethanol is: - C: 52,13 % - O: 34,74 % - H: 13,13 %
The percent composition of manganese dichoride (MnCl2) is: - Mn: 44 % - Cl: 56 %
The percent composition of nitrous oxide is: - N: 63,649 % - O: 36,351 %
