Balanced Equation:
2PbS+ O2 --> 2PbO +2SO2


How many grams of oxygen are required to react with 0.124mole lead(II) sulfide?

Ummmm.. I tried to convert it to grams?
0.124 mol * molar mass of PbS (239.3) = 29.67 g of PbS then tried to plug it into the equation..
1/2 * 29.67/239.3 *32 = 1.98 g?? but that's wrong?? Help please?

You don't convert anything to grams. Use mols to convert from what you have to what you want. Then convert to grams. Reactions go by mols, not grams.
