We are asked to determine the molecular formula of a compound Estradiol with a molar mass of 272.37 g/mol and percentage composition of 79.37% C, 8.88% H, 11.75% O.

This means we need to do the following steps:


Step 1: Calculate the mass and moles of C, H, and O in the compound.

Step 2: Determine the lowest whole number ratio of C, H, and O to get the empirical formula.

Step 3: Get the ratio of the molar mass and empirical mass to determine the molecular formula.
