Chemistry questions and answers. 10. A sample of polluted water was analyzed for lead (II) ion, by adding an excess of sodium sulfate to it. The excess sodium sulfate reacted with all the lead ion, and 135.6 mg of lead (II) sulfate precipitated. The mass of polluted water tested was 23.700 kg and the density of the sample solution was 1.021 g/mL.Click here👆to get an answer to your question ️ The solubility of PbSO4 water is 0.038 g/L. Calculate the solubility product constant of PbSO4 . Molar mass PbSO4 = 304 g/mole 380304 = 1.25 (1.25)^2 = 1.56The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, every element in Pb + NiSO4 = PbSO4 + Ni2 must have the same number of atoms on each side of the equation.

The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, every element in PbO + Pb + H2SO4 = PbSO4 + H2O must have the same number of atoms on each side of the equation.Chemistry. Chemistry questions and answers. 2. A sample of polluted water was analyzed for lead (11) ion, Pb2+ (molar mass = 207.2 g/mol), by adding excess sodium sulfate to it. The mass of lead (II) sulfate, PbSO4 (molar mass = 303.26 g/mol), that precipitated was 0.2298 g. Use stoichiometry calculations to determine the mass of lead in the ...Computing molar mass step by step. First, compute the number of each atom in PbCO 4: Pb: 1, C: 1, O: 4. Then, lookup atomic weights for each element in periodic table: Pb: 207.2, C: 12.0107, O: 15.9994. Now, compute the sum of products of number of atoms to the atomic weight: Molar mass (PbCO 4) = ∑ Count i * Weight i =.
