Performing metabolomics pathway analysis using metabolites molecular weight or molecular formulas

I have a general question regarding metabolomics analysis and would appreciate any help/insights.

I have a list of unknown/unannotated metabolites. The only 2 pieces of information I have are molecular weight and/or molecular formula (an example is in the attached csv file). I want to ask whether I may perform an enrichment (pathway) analysis using this information.

Many thanks to you in advance for your help.
