Answer:
3.05 g
Explanation:
The reaction that takes place is:
- 4HCl + O₂ → 2Cl₂ + 2H₂O
As the decomposition not necessarily was complete we'll work with the<em> given mass of product formed</em>. We convert <u>the 12 grams of chlorine to moles</u>, using its <em>molar mass</em>:
- 12 g ÷ 70.906 g/mol = 0.169 mol
Then we <u>convert Cl₂ moles to H₂O moles</u>:
- 0.169 mol Cl₂ *
= 0.169 mol H₂O
Finally we <u>convert moles to grams</u>:
- 0.169 mol H₂O * 18 g/mol = 3.05 g
