The two oxides of carbon described on page 38 were CO and Another oxide of carbon has 1.106 g of oxygen in a 2.350 g sample. In what ratio are carbon and oxygen atoms combined in molecules of this third oxide? Explain.

Expert Solution

Assuming the intermediate is “half-way” between CO and CO₂, then the oxygen- carbon ratio would be 2:1, or O:C = 24:12. This mass ratio gives a mole ratio of O:C = 1.5:1. Empirical formulas are simple whole number ratios of elements; hence, a formula of C₃O₂ must be the correct empirical formula for this carbon oxide.

Given CO and CO₂, with an intermediate, O:C ratio is 2:1, equating to 1.5:1 mole ratio. Empirical formula: C₃O₂.
