Step 1: Write the balanced chemical equation for the neutralization reaction. Mg(OH)_2 + 2HCl MgCl_2 + 2H_2O Step 2: Determine the mole ratio from the balanced equation. 1 mol Mg(OH)_2 neutralizes 2 mol HCl. Moles of Mg(OH)_2 required for 1 mol HCl: n_Mg(OH)_2 = 1~mol~HCl2~mol~HCl/mol~Mg(OH)_2 = 0.5~mol~Mg(OH)_2 Step 3: Calculate the molar mass of Mg(OH)_2. Atomic masses: Mg = 24.3 g/mol, O = 16.0 g/mol, H = 1.0 g/mol. M_Mg(OH)_2 = 24.3 + 2×16.0 + 2×1.0 = 24.3 + 32.0 + 2.0 = 58.3~g/mol Step 4: Calculate the mass of Mg(OH)_2 required. Formula: mass = moles × molar mass. m_Mg(OH)_2 = 0.5~mol × 58.3~g/mol = 29.15~g ≈ 29.16~g 29.16 g
