Total number of nucleons in 0.02 g of hydrogen gas is: [1] — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Moles of $H_2 = 0.02 / 2 = 0.01$ mol. <br>Number of $H$ atoms $= 0.01 \times 2 \times N_A = 0.02 N_A$. <br>Each $H$ atom (protium) has 1 nucleon (1 proton). <br>Total nucleons $= 0.02 \times N_A = 2 \times 10^{-2} N_A$. [1]
