How is the percentage of oxygen determined in the quantitative estimation of organic compounds?
(N/A) $(i)$ $\% O = 100 - (\text{Sum of percentages of all other elements in the compound.})$
$(ii)$ Alternatively,it can be calculated using the formula: $\% O = \frac{32}{88} \times \frac{\text{mass of } CO_2 \text{ formed}}{\text{mass of organic compound}} \times 100$
