How to Use the Stoichiometry PYQ PDF for MHT CET

Start with the 2025 and 2026 papers first, because they hold 1 of the 1 questions.
Use the law of conservation of mass: the mass of oxygen is the mass of the product minus the mass of carbon.
Solve year-wise PYQs by timing yourself, as time management is crucial.
Re-attempt only the questions you got wrong, and note which formula or step you missed.
