Answer:
Option a → 111.9 g
Explanation:
The reaction is this:
2KClO₃ → 2KCl + 3O₂
2 moles of chlorate decompose to 2 moles of chloride and 3 moles of oxygen. Ratio is 2:2.
If I use 1.5 moles of chlorate I'll get the same moles of chloride by the decomposition.
Let's convert the moles to mass: 1.5 mol . 74.6 g / 1mol = 11.9 g
