4. Consider the following reaction. 2 PbS (s)+3 O2 (g) 2 PbO (s) + 2 SO2 (g) [Balanced] When 3.45 g of lead(II) sulfide (PbS) are reacted with excess oxygen gas, the mass of lead(II) oxide (PbO) produced was 2.87 g. Calculate the percent yield of the reaction. Use the molar mass data below if necessary. Show all your work. (10 points) Molar mass of PbS = 239.3 g/mol Molar mass of O2 = 32.00 g/mol Molar mass of PbO = 223.2 g/mol
