Answer:
8.67 mol SnO₂
Explanation:
Step 1: Write the balanced equation for the decomposition reaction of SnO₂ to produce Sn
SnO₂(s) ⇒ Sn(s) + O₂(g)
Step 2: Establish the appropiate molar ratio
According to the balanced equation, the molar ratio of SnO₂ to Sn is 1:1.
Step 3: Calculate the moles of SnO₂ required to produce 8.67 moles of Sn
We will use the established molar ratio.
8.67 mol Sn × 1 mol SnO₂/1 mol sn = 8.67 mol SnO₂
