3. Determine the theoretical oxygen demand (i.e., \( \mathrm{mg} \mathrm{O}_{2} \)-demand per \( \mathrm{mg} \) of compound)

3. Determine the theoretical oxygen demand (i.e., \( \mathrm{mg} \mathrm{O}_{2} \)-demand per \( \mathrm{mg} \) of compound) for the following compounds: (a) Glycerol \( \left(\mathrm{C}_{3} \mathrm{H}_{8} \mathrm{O}_{3}\right) \) (b) Lactose \( \left(\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11}\right) \) (c) Linolenic acid \( \left(\mathrm{C}_{18} \mathrm{H}_{30} \mathrm{O}_{2}\right) \) (d) Xylitol \( \left(\mathrm{C}_{5} \mathrm{H}_{12} \mathrm{O}_{5}\right) \)
