We can use the formula for weight percent: weight percent = (mass of solute ÷ mass of solution) × 100% First, we need to convert the mass of LiCl to grams: 27.9 g LiCl Next, we need to calculate the mass of the solution by adding the mass of H₂O to the mass of LiCl: 27.9 g LiCl + 175 g H₂O = 202.9 g solution Now we can use the formula: weight percent = (mass of LiCl ÷ mass of solution) × 100% weight percent = (27.9 g ÷ 202.9 g) × 100% weight percent = 0.137 × 100% weight percent = 13.7% Therefore, the weight percent of LiCl in the solution is 13.8%, which is closest to choice (C).
