The image presents a chemical structure of a bicyclic compound, featuring a lactone (cyclic ester) with an ether linkage and a methoxy group. One of the rings contains an oxo group (C=O). The double-bonded oxygen acyl group introduces a point of asymmetry to the molecule. 

Below the structure, there are several tasks:

1. **Tasks:**
   - a) Determine the molecular formula. *(Task crossed out)*
   - b) Calculate the molecular mass. *(Task crossed out)*
   - c) Determine the stereochemistry of all stereocenters. Use R/S and E/Z designations where applicable.
   - d) On a drawing of your compound, label homotopic protons by numbering the homotopic groups. *(Task crossed out)*

The structure requires analyzing the stereochemistry due to the presence of chiral centers, indicated by the wedge and dashed bonds. The objective is to assign absolute configurations to these stereocenters using the Cahn-Ingold-Prelog priority rules. 

The molecule can be further characterized by determining the R/S stereochemistry of the chiral centers, considering priorities based on atomic numbers and connectivity.
