**Calculate CaCo3 + 2HCl â†’ CaCl2 + CO2 + H2O? Yahoo Answers**

A 0.5444 g sample is treated with 50 mL of 0.1007 M HCl. The excess acid requires 24.5 mL of 0.02510 M NaOH be neutralized. I'm not sure how to go about solving for the MASS PERCENTAGE of CaCO3..... 7/05/2011Â Â· An antacid tablet is known to contain calcium carbonate (CaCO3). To determine the mass of calcium carbonate int he tablet, the following procedure was used. -The tablet was crushed and then placed in a beaker. -A pipette was used to add 25.0mL of 0.600mol L-1 hydrochloric acid to the crushed tablet in the beaker. -Once the reaction

## How To Find Mass Of Caco3

### Later, if we can find out the number of mole of unreacted acid, number of mole of calcium carbonate can then be found out. The number of mole of unreacted acid can be found by titration with the following reaction: HCl(aq) + NaOH(aq) â†’ H2O(l) + NaCl(aq) Percentage by mass of calcium carbonate in eggshell can then be calculated by the following formula: % by mass of CaCO3 = Requirements

- To find the percentage mass of one of these elements, divide the molar mass of the element by the total molar mass of the compound (add them all up, using oxygen three times), then multiply by 100%. Molar mass of CaCO3 = 40.08 +12.01 + 3*16.00 = 100.09 g/mol
- Molecular mass of CaCO3 =sum of all the masses of its components.Ca=40u O=16u C=12u Molecular mass=40+12+3x16 =40+12+48 =100u Therefore, molar mass of CaCO3 is 100g
- There you can find the density, molar mass, and molecular formula. This information should be sufficient to calculate the mass of CaCO3 in a large variety of situations. This information should be sufficient to calculate the mass of CaCO3 in a large variety of situations.
- Find an answer to your question calculate molar mass- CacO3
