Stoichiometry of Gases and Molar Volume
Apply stoichiometric principles to reactions involving gases, using concepts like molar volume at STP and gas density calculations.
Why this shows up in the exam
Exams frequently test your ability to relate gas volumes, molar volumes, and densities to chemical equations and reaction stoichiometry.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
At STP the density of CCl₄ vapour in g/L will be nearest to
Push further
More challenging1 harder question built from the past papers above — a step up in difficulty, with distractors designed so you can't get there by elimination. Written and checked by our reviewers, not from a real paper.
What volume of oxygen gas (O₂) at STP can be produced from the complete decomposition of 24.5 g of potassium chlorate (KClO₃)? The reaction is 2KClO₃(s) → 2KCl(s) + 3O₂(g).
