What is the mass ratio of lead per gram of oxygen in the two compounds?

Solve for the masses of oxygen given 1 gram of Pb:For PbO:(1 g Pb)(1 mol Pb/207.2 g Pb)(1 PbO/1 Pb)(1 O/1 PbO)(16 g O/1 mol O) = 0.07722 g OFor PbO2:(1 g Pb)(1 mol Pb/207.2 g Pb)(1 PbO2/1 Pb)(2 O/1 PbO2)(16 g O/1 mol O) = 0.1544 g OFor Pb2O3:(1 g Pb)(1 mol Pb/207.2 g Pb)(1 Pb2O3/2 Pb)(3 O/1 Pb2O3)(16 g O/1 mol O) = 0.1158 g OGet the ratio by dividing the smallest mass of oxygen to the rest of the calculated masses then multiply it by a certain factor to make it a whole number:0.07722 / 0.07722 = 1 x 2 = 20.1544 / 0.07722 = 2 x 2 = 40.1158 / 0.07722 = 1.5 x 2 = 3ANSWER: 2:4:3
