percentage is the same as grams so you just get the atomic weight and add them together
ex: Ca- 40, C- 12, 03- 48 (16+16+16)
then add them all together to get the grams
40+12+48=100 g or 100%
To work out the percentage mass of carbonate in CaCO3, you must first find the releative molecular mass of the CO3, and the relative molecular mass of the whole compound. To do this, you just need to add up their respective mass numbers: r.m.m. of CO3: 12 + 16 + 16 + 16 [one carbon atom plus three oxygen atoms] = 60 r.m.m of CaCO3: 40 + 12 + 16 + 16 + 16 [one calcium + one carbon + three oxygen atoms] = 100 To work out the percentage mass of the carbonate in the compound, you divide the 60 by the 100. This gives 0.6, which is 60%.
Its just the number of elements in the equation...so it would be 1Calcium, 1Carbon, and 3 Oxygens.
The percent composition of calcium hydrogen carbonate is:
- calcium: 24,691 %
- hydrogen: 1,235 %
- carbon: 14,814 %
- oxygen: 59,259 %
40g/56g x 100%
40 / (40+60) = 40%
40+12*2=64
In terms of the number of atoms it is 50%. In terms of mass, it is 5.88%.
99 percent of the human body contains carbon, oxygen and hydrogen atoms. The composition of hydrogen in human body is 9.5 percent.

Calcium Chloride Carbon Dioxide and Water: CaCO3 + 2HCl -> CaCl2 + CO2 + H2O
Calcium is derived from the Latin word for a pebble or a small stone, calculus. It was probably named that because most stones contain a high percent of calcium salts, as chalk is Calcium Carbonate.
The percent composition by element of Ca(C2H3O2)2 is calcium 25.339%, hydrogen 3.824%, carbon 30.375%, and oxygen 40.462%.
Calcium percent in CaCO3: 65,196 %
BeCO3 Oxygen - 69,56 %; Carbon - 17,39 %; Beryllium - 13,04 %.
Can you be more specific? Percent composition is usually the percent of an element in a compound.
Echinoderms have an Endoskeleton made up of 95 % calcium carbonate.
10 to 20 percent
Yes it is although there are other things that make marble up swell as calcium carbonate but it is mostly that !

The cell of a chicken egg is made up of about 94 percent calcium carbonate(Ca(CO3)2), 1 percent magnesium carbonate, 1 percent calcium phosphate, and about 4 percent organic matter, mainly protein.
The molar mass of calcium carbonate (CaCO3) is 100.09 g/mol. To calculate the percent mass of calcium, you need to divide the molar mass of calcium (40.08 g/mol) by the molar mass of calcium carbonate. This gives you a result of 0.4006, meaning that calcium constitutes approximately 40.06% of the mass of calcium carbonate.
