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%

∙ 14y agoTo 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%.

What will be formed when 15 percent of hdrochloric acid is added to calcium carbonate?
Calcium Chloride Carbon Dioxide and Water: CaCO3 + 2HCl -> CaCl2 + CO2 + H2O
What is the reason for naming calcium?
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.
What is the percent composition of acetate?
The percent composition by element of Ca(C2H3O2)2 is calcium 25.339%, hydrogen 3.824%, carbon 30.375%, and oxygen 40.462%.

What is the molecular structure of an eggshell?
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.
What is the percent mass of calcium in a calcium supplement if 1.35-g of calcium carbonate is extracted from a 2.36-g pill?
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.
