Solubility in water, ethanol, . Barium Carbonate BaCO3 Molar Mass, Molecular Weight. BaCO 3: Barium Carbonate: Density: 4.29 g/cm³: Molecular Weight/ Molar Mass: 197.34 g/mol: Boiling Point: 1,360 °C: Melting Point: 811 °C: Chemical Formula: BaCO 3 We have to assume, because we don't know the mass of Na2CO3, that BaCl2 is the limiting factor in this reaction. Point Group: 2/m 2/m 2/m. Witherite BaCO3 c 2001-2005 Mineral Data Publishing, version 1 Crystal Data: Orthorhombic. More information about Barium carbonate (BaCO3). Th... See full answer below. Assume all the carbon originally present is converted to carbon dioxide. . Moles = Mass given/Molar mass. The molar mass of BaCO 3 is 197.3359 g/mol. What percentage of BaCO3 did the sample contain? I really have no idea where to even begin with this. One carbon atom has a molar mass of 12.0107 g/mol. To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets. A sample that contains only SrCO3 and BaCO3 weighs 0.651 g. When it is dissolved in excess acid, 0.161 g carbon dioxide is liberated. One barium atom has a molar mass of 137.327 g/mol. As BaCl2 and NaCl are in a 1:2 molar ratio from the given equation that twice the moles of BaCl2 are formed; 0.025 (moles of BaCl2) X 2= 0.05 moles of NaCl To find more Barium carbonate information like chemical properties, structure, melting point, boiling point, density, molecular formula, molecular weight, physical properties and toxicity information. • Ba(HCO3)2 = BaCO3 + H2O + CO2 5.3g of BaCl2 / 208.23 g/mol = 0.025 moles.
