Sagot :
Answer:
2.042 g
Explanation:
The reaction that takes place is:
- 2HCl + Mg(OH)₂ → Mg²⁺ + 2Cl⁻ + 2H₂O
First we calculate how many HCl moles were added, using the given volume and concentration:
- 30 mL ⇒ 30 / 1000 = 0.030 L
- 5.6 M * 0.030 L = 0.168 mol HCl
Then we convert HCl moles into Mg²⁺ moles, using the stoichiometric coefficients:
- 0.168 mol HCl * [tex]\frac{1molMg^{+2}}{2molHCl}[/tex]= 0.084 mol Mg⁺²
Finally we convert Mg moles into grams, using its molar mass:
- 0.084 mol Mg⁺² * 24.305 g/mol = 2.042 g
