of on being strongly heated yields a residue weighing: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$Ag_2CO_3 \rightarrow 2Ag + CO_2 + 1/2 O_2$. <br>MW of $Ag_2CO_3 = 2(108) + 12 + 48 = 276\text{ g/mol}$. <br>$\text{Moles} = 2.76 / 276 = 0.01$. $\text{Moles of } Ag \text{ residue} = 0.02$. <br>$\text{Mass} = 0.02 \times 108 = 2.16\text{ g}$.
