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

💡 Solution & Explanation

$\text{Moles of } H_2 = 0.02/2 = 0.01$. $\text{Atoms} = 0.02 N_A$. Each $H$ atom has 1 nucleon (proton). $\text{Total nucleons} = 0.02 N_A = 2 \times 10^{-2} N_A$. [2]
