AI Generated Solution

To solve the problem, we need to calculate the boiling point elevation of the aqueous solution containing glucose. Here are the steps to find the solution: ### Step 1: Identify the given data - Boiling point of pure water, \( T_b^0 = 373 \, \text{K} \) - Mass of glucose (solute), \( m_{solute} = 18 \, \text{g} \) - Molar mass of glucose, \( M_{glucose} = 180 \, \text{g/mol} \) - Mass of water (solvent), \( m_{solvent} = 100 \, \text{g} \) - Molal elevation constant of water, \( K_b = 0.52 \, \text{K kg/mol} \) ...
