Question Style in MHT CET Mole Concept PYQs
Every question in this PDF is a single-correct MCQ. Each one is a short calculation that converts between mass, moles, number of particles and volume at STP.
| Question Style | What it Tests |
|---|---|
| Number of molecules or atoms | The molecules in 2.125 g of ammonia, in 70 g of dinitrogen and in 2.24 dm³ of carbon dioxide at STP, and the hydrogen atoms in 5.4 g of urea |
| Electrons and ions | The electrons in 3.2 g or 1.6 g of methane, and the Cl⁻ or Ca²⁺ ions in 222 g of anhydrous calcium chloride |
| Moles from mass or volume | The millimoles in 0.160 g of sodium hydroxide, the moles in 0.448 L of dihydrogen at STP, and the moles of urea in 5.4 g |
| Mass and percentage composition | The percentage by mass of oxygen in NaOH, the percentage of carbon in urea, and the mass in grams of 0.25 mol of water |
| Volume at STP | The volume of 56 g of dinitrogen, the volume of 8 g of a gas of vapour density 16, and the oxygen needed to burn 0.25 mole of methane |
How to Use the Mole Concept PYQ PDF for MHT CET
- Start with the 2025 and 2026 papers first, because they hold 22 of the 43 questions.
- Keep three conversions on one line: moles = mass / molar mass, number of particles = moles × 6.022 × 10²³, and volume at STP = moles × 22.4 L.
- For electron and ion counts, write the number of electrons or ions per formula unit first and then multiply.
- 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.
