The ratio of universal gas constant and molar mass of gas is called molar gas constant. The value of — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

specific gas constant r = r / m. since r is constant, r is inversely ∝ molar mass m. among the given options, h2 has the lowest molar mass (m = 2 g/mol), so its specific gas constant is the largest.
