The formula for molality is moles of solute per kilogram of solvent. First, we need to convert the given X_LiCl to moles per gram of water: 0.00900 mol LiCl / 18.015 g H2O = 0.000499 mol LiCl/g H2O Next, we need to convert from grams of water to kilograms of water: 1000 g H2O / 1 kg H2O So, the molality of the solution is: 0.000499 mol LiCl / 1 kg H2O = 0.549 mol/kg H2O = 0.549 m LiCl Therefore, the answer is C: 5.49 m LiCl.
