Lead (II)carbonate decomposes to give lead (II)oxide and carbon dioxide: PbCO₃ (s) → PbO (s) + CO₂ (g) ________ grams of lead (II)oxide will be produced by the decomposition of 8.75 g of lead (II)carbonate? A)0.41 B)2.50 C)0.00936 D)7.31 E)11.7

Question

Quizplus · Accepted Answer

The molar mass of PbCO₃ is approximately 267.21 g/mol, and the molar mass of PbO is approximately 223.2 g/mol. The decomposition of 8.75 g of PbCO₃ produces (8.75 g / 267.21 g/mol) moles of PbCO₃, which equals the moles of PbO produced. Multiplying by the molar mass of PbO gives approximately 7.31 g of PbO.
