Answer:
2.042 g
Explanation:
The reaction that takes place is:
- 2HCl + Mg(OH)₂ → Mg²⁺ + 2Cl⁻ + 2H₂O
First we <u>calculate how many HCl moles were added</u>, using <em>the given volume and concentration</em>:
- 30 mL ⇒ 30 / 1000 = 0.030 L
- 5.6 M * 0.030 L = 0.168 mol HCl
Then we<u> convert HCl moles into Mg²⁺ moles</u>, using the<em> stoichiometric coefficients</em>:
- 0.168 mol HCl *
= 0.084 mol Mg⁺²
Finally we <u>convert Mg moles into grams</u>, using its<em> molar mass</em>:
- 0.084 mol Mg⁺² * 24.305 g/mol = 2.042 g
