Which of the following statements is/are correct? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

1 amu is $1/N_A$ g. <br>$\text{Mass of 1 mole } e^- = (9.1 \times 10^{-28} \text{ g}) \times (6.022 \times 10^{23}) \approx 0.000548 \text{ g} = 0.548 \text{ mg}$. <br>$\text{Mass of 1 mole } p^+ \approx 1.007 \text{ g} \approx 1 \text{ g}$. <br>22.4 L is the standard molar volume at STP.
