% K =2 x 39.1 x 100/ 138.2 =56.6
% C = 12 x 100/ 138.2 =8.68
% O = 3 x 16 x 100/ 138.2 =34.7
Potassium = 56.6 %

What is the mass percent of nitrogen in ammonium carbonate (NH4)2CO3?
The percentage of nitrogen is 29,16 %.
What percent of carbon by mass in C17H19NO3?
The percentage of carbon is 71,58 %.
What mass of carbon dioxide is formed when 125g of zinc carbonate decomposes?
125 g of Zinc Carbonate is 1 mole and when it decomposes it forms 1 mole of Carbon Dioxide ZnCO3 = ZnO + CO2 1 mole of carbon dioxide has a mass of 44g 44g is the answer
What is mass of calcium carbonate is to be decomposed to obtain 4.4 gram of carbon dioxide in the reaction caco3-cao plus o2?
The equation given shows that each formula mass of calcium carbonate produces one formula mass of CO2. The gram formula masses of calcium carbonate and carbon dioxide are 100.09 and 44.01 respectively. Therefore, to produce 4.4 grams of carbon dioxide, 4.4(100.09/44.01), or 10 grams of calcium carbonate, to the justified number of significant digits, are needed.

125 g of Zinc Carbonate is 1 mole and when it decomposes it forms 1 mole of Carbon Dioxide ZnCO3 = ZnO + CO2 1 mole of carbon dioxide has a mass of 44g 44g is the answer
How do you calculate the theoretical mass percentage of oxygen in potassium chlorate?
I believe it is: %O=mass of 3 mol of O / mass of 1 mol of potassium chlorate *100% If you measured it: %O=mass of oxygen lost / mass of potassium chlorate *100%

What gives off more carbon dioxide when mixed with hydrochloric acid - chalk or marble?
Important is the percentage of calcium carbonate (CaCO3) in the material. For an equivalent mass of pure chalk or pure marble the quantity of released carbon dioxide is the same - the chemical formula is the same.
