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)

1.0 times 10^3
PbCO_3
PbSO_4
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
