A student has a sample of the mixed salt PbCO3 X Pb(OH)2. In a mixed salt two compounds are mixed together in one crystal. X represents the mole ratio between the two compounds, and is usually a small whole number. The student heats the sample with sulfuric acid which causes the salt to react completely, producing PbSO4(s), CO2(g) and H₂O as the products. If 4.560 g of PbSO4 and 0.1656 g of CO2 are produced in the reaction, what is the value of X for this particular mixed salt? PbCO3 [Select ] Pb(OH)2 (select the value for "X" in PbCO3 X Pb(OH)₂)
