Practice question

Given: What is the SI unit of a physical quantity with dimensional formula [M L² T^{-2 K^{-1 mol^{-1] using only base units? Formula: Base units: [M] = kg, [L] = m, [T] = s, [K] = K, [mol] = mol. Substitution & Calculation: [M L² T^{-2 K^{-1 mol^{-1] = kg m² s^{-2 K^{-1 mol^{-1 . (Matches gas constant). Final Result: The computed value matches expected outcome and confirms correct choice as per latest NCERT 2026-27.
