Question Style in MHT CET Ideal Gas Equation PYQs
Every question in this PDF is a single-correct MCQ. Most are short substitutions into PV = nRT, and the units of R need care.
| Question Style | What it Tests |
|---|---|
| Moles from P, V and T | The moles of CO₂ in 4 × 10⁻³ m³ at a given pressure and temperature, and the moles of dioxygen in a given volume at 318 K |
| Pressure of a gas | The pressure of 3.4 moles of an ideal gas in 68 mL at 300 K, and of 2 moles at 546 K in 44.8 L |
| Temperature of a gas | The temperature in °C when the volume and pressure of 2 moles of an ideal gas are given |
| Gas constant and STP | The numerical value of R in L atm K⁻¹ mol⁻¹, the number of moles in 1 m³ of any gas at STP, and the density of water vapour at the boiling point of water |
| Dissolved gas | The volume of dissolved CO₂ in a cold drink bottle, treated as an ideal gas |
How to Use the Ideal Gas Equation PYQ PDF for MHT CET
- Start with the 2025 and 2026 papers first, because they hold 3 of the 12 questions.
- Pick the value of R that matches the units given in the question, and convert dm³ and mL to m³ or L before substituting.
- Memorise the molar volume at STP, 22.4 L for 1 mole, because several questions use it directly.
- 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.
