The sulfur atom forms with oxygen atoms two complex substances (they are called oxides) of different composition. The relative molecular weight of the first oxide is 64, and the second – 80. Derive the formulas of these oxides.
The oxide necessarily contains an atom of sulfur and oxygen,
subtract from the relative molecular weight the relative
atomic oxygen and sulfur. We look and make up the formulas of the substance:
Mr (SO2) = 16 + 16 + 32 = 64 g
Mr (SO3) = 16 + 16 + 16 + 32 = 80 g
