Question

Lead can form two compounds with oxygen- determine the formulas from the following data:
A lead oxide compound (compound A) was found to have a mass of 0.239g. It was heated, and the oxygen was removed. The remaining lead (Pb) had a mass of 0.207g. Please put answers to the correct number of significant figures!

Compound A:
1.Mass of Pb
2.Mass of O
3.Moles of Pb( show work)
4. Moles of O (show work)
5 formula of compound A

Another lead oxide compound ( compound b) had a mass of 0.446 g. It was heated, and the oxygen was removed. The remaining lead (Pb) had a mass of 0.414g.

Compound B
1. mass of Pb
2. Mass of O
3. Moles of Pb (show work)
4. Moles of O ( show work)
5. Formula of Compound B

Thanks!

Explanation / Answer
