The Mole, at Full Speed ⏱️
60 seconds of mole-concept numericals with NEET scoring (+4 / −1). Fresh questions every run. Mole concept = Chemistry ka F = ma — master it here! 🧪
🧮 Constants used: molar volume at STP = 22.4 L (273 K, 1 atm — the value NEET papers usually give; NCERT's new STP of 273.15 K and 1 bar gives 22.7 L, so always use the value the question states) · Avogadro number written as NA · clean masses (H₂O=18, CO₂=44, NaOH=40, CaCO₃=100, glucose=180…)
