Calculate the total mass of of atoms in grams, given mass of proton and electron . — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
Calculate the total mass of $1 \text{ mole}$ of $^1\text{H}$ atoms in grams, given mass of proton $= 1.672 \times 10^{-24} \text{ g}$ and electron $= 9.1 \times 10^{-28} \text{ g}$.
Answer: $1.008 \TEXT{ G}$
💡 Solution & Explanation
$\text{Mass of 1 atom} = 1.672 \times 10^{-24} + 9.1 \times 10^{-28} \approx 1.673 \times 10^{-24} \text{ g}$. <br>$\text{Mass of 1 mole} = 1.673 \times 10^{-24} \times 6.022 \times 10^{23} \approx 1.008 \text{ g}$.
