To find the percentage of silver in the ore sample, we can follow these steps: ### Step 1: Calculate the moles of Ag₂S We know that the mass of Ag₂S produced is 0.125 g. We need to calculate the molecular weight of Ag₂S first. - **Molecular weight of Ag₂S**: - Silver (Ag) = 108 g/mol - Sulfur (S) = 32 g/mol ...
