Interpretation Introduction To determine: The amount of rock to be processed. Explanation Given: The mass percentage of PbS is 38.0 % . The mass percentage of PbCO 3 is 25.0 % . The mass percentage of PbSO 4 is 17.4 % . The mass of lead is 5.0 metric ton . Explanation: According to the mass percentages, the mass of PbS is 38.0 kg , the mass of PbCO 3 is 25.0 kg , and the mass of PbSO 4 is 17.4 kg . Calculate mass of Pb in PbS as follows: Mass of Pb = Mass of PbS × Molar mass of Pb Molar mass of PbS = 38.0 kg × 207 g/mol 239.1 g/mol = 32.9 kg Calculate mass of Pb in PbCO 3 as follows: Mass of Pb = Mass of PbCO 3 × Molar mass of Pb Molar mass of PbCO 3 = 25.0 kg × 207 g/mol 267 g/mol = 19
