Problem 70P

Lead is found in Earth’s crust as several lead compounds. Calculate the mass (in kg) of each compound that contains $$1.0 \times 10^{3}$$ kg of lead.

(a) PbS (galena)

(b) $$\mathrm{PbCO}_{3}$$ (cerussite)

(c) $$\mathrm{PbSO}_{4}$$ (anglesite)

Equation Transcription:   Text Transcription:

1.0 times 10^3

PbCO_3

PbSO_4

Step-by-Step Solution:

Step 1 of 3

Here, we have to calculate the mass of each compound that contains kg of lead.

Molar mass of Pb = 207.2  g/mol

(a) PbS Molar ratio = 1:1

Molar mass of PbS = 239.3 g/mol

Mass of PbS = 1000 g  = 1154.9 g = 1.1549 Kg

Thus, mass of PBs is  = 1.1549 Kg
