Determine the molecular formula of the compound. Give the exact structural formula and name of compound A

Here are the solutions to the questions.

i. Determine the empirical formula of the compound

Step 1: Calculate the mass of Oxygen (O).
The total mass of compound A is $1 \text{ g}$.
Mass of Carbon (C) $= 0.400 \text{ g}$
Mass of Hydrogen (H) $= 0.133 \text{ g}$
Mass of Oxygen (O) $= \text{Total mass} - \text{Mass of C} - \text{Mass of H}$
