What is the total number of protons present in of ? (Express as ) — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{moles } CaCO_3 = 10 / 100 = 0.1$. <br>Protons per $CaCO_3 = 20(Ca) + 6(C) + 24(O) = 50$. <br>Total protons $= 0.1 \times 50 \times 6.022 \times 10^{23} \approx 3 \times 10^{24}$. <br>Thus, $x = 3$.
