Answer:
To determine the molecular formula of the compound, we need to find the empirical formula first.
1. Calculate the moles of each element:
Moles of carbon = 75.46% / atomic mass of carbon
Moles of hydrogen = 4.43% / atomic mass of hydrogen
Moles of oxygen = 20.10% / atomic mass of oxygen
2. Find the ratio of moles of each element. Divide each value by the smallest of the three.
3. The resulting ratio will give you the empirical formula.
4. Calculate the empirical formula mass.
5. Finally, find the multiplier to obtain the molecular formula by dividing the given molecular weight by the empirical formula mass.
Performing these calculations will give you the molecular formula of the compound.
