Jan 04, 2008· a gram sample of a mixture of CaCo3 and Na2SO4 was analyzed by dissolving the sample and completely precipitating the Ca2t as CaC2O4. The CaC2O4 was dissolved in sulfuric acid and the resulting H2C2)4 was titrated with a standard KMnO4 solution. This was a four part question. I''ve got the first four parts, which involved balancing an equation and calculating moles of certain .

Sep 30, 2008· of CaCO3 is dissolved in HCl. the excess HCl is put into a beaker where 50ml of mol/L of NaOH is added along with acidbase indicator. titration is used and determined that ml of mol/L of HCl are needed for titration. What is the percentage of CaCO3 in the marble? I am so lost with this question. Any help is well appreciated.
n(HCl reacted with calcium carbonate) = × 103 = × 103 mol Write the balanced chemical equation for the reaction between calcium carbonate in the chalk and the HCl (aq). CaCO 3 (s) + 2HCl (aq) → CaCl 2(aq) + CO 2(g) + H 2 O (l) From the balanced chemical equation, calculate the moles of CaCO 3 that reacted with HCl.
Sep 25, 2007· For the best answers, search on this site https:///axFE9. In order to solve this we need an equation although it doesn''t matter what the acid is, let''s use HCl. CaCO3 + HCl > CO2 + CaCL2 + H20 note that there is a 1 to 1 molar ratio of CO2 to CaCO3 that is each mole of CaCO3 reacted produces 1 mole of CO2.
To calculate molecular weight of a chemical compound enter it''s formula, specify its isotope mass number after each element in square brackets. Examples of molecular weight computations: C[14]O[16]2, .
Apr 22, 2013· Mass of CaCO3 = g . And mass of MgCO3 = 192 = g. Now to calculate the volume of CO2. g CaCO3 = /100 = mol. g MgCO3 = /84 = mol. From equations (1) and (2) it is evident that 1mol CO2 is formed both from 1 mol CaCO3 and 1 mol MgCO3. mol CaCO3 will yield mol CO2

Oct 09, 2008· The mass of the marble sample = The Volume of HCL is 50mL = (and it is /L solution) The Volume of the NaOH = mL. The Concentration of NaOH = mol/L. It wants me to calculate te percent of marble in CaCO3 .
calcium carbonate and a number of other ingredients as listed on the bottle. Only calcium carbonate produces gas in the reaction with HCl(aq). Use a mass of approximately g. The sample can be used as a chunk; it does not need to be pulverized. Record the exact mass used. Record the four volume readings as per Steps 6 and 8 above.
Mar 18, 2013· Molar mass of CaCO3 = 100 g /mol Mass of CaCO3 = mol X 100 g/mol = g percentage by means of weight of CaCO3 within the sample; %W = (Mass of the CaCO3 / complete mass of the pattern)X100 %W = ( g / g) X .
Sep 05, 2008· Then I had to calculate moles base in sample (3 trials averaged ), moles base in tablet (average of ), mg CaCO3 in sample (), and mg CaCO3 in tablet. The average mg CaCO3 in tablet from the 3 trials I calculated to be, but that seems really high.
Nov 02, 2011· Marble is composed mainly of calcium carbonate, CaCo3. If of marble reacts with hydrochloric acid to produce 165mL of carbon dioxide at STP, what is the percentage of calcium chloride in the sample? CaCo3 (s) + 2HCl (aq) > CaCl2 (aq) + H2O (l) + CO2 (g)
The percent composition of a compound tells the amount of each element in the compound as a percentage. It is possible to find if the mass of an element and the total mass of the compound is known.
Calcium Carbonate Formula. It is a chemical compound with the chemical formula CaCO 3.; It is a white insoluble powderlike substance which occurs naturally in minerals, chalk, marble, limestone, calcite, shells, pearl, etc.; Medicinally, it is used as an antacid or as a calcium supplement.
