**Text Transcription for Educational Website:**A solution containing 6.314 g of a non-volatile organic solute dissolved in 100.00 g of toluene boils at 384.72 K at 1 bar of pressure. The boiling point of pure toluene is 383.75 K and Δ_vapH = 38.06 kJ/mol for benzene.(a) What is the boiling point elevation constant for toluene? (units: kg·K/mol)(b) What is the molar mass (g/mol) of the unknown solute?**Explanation:**This problem involves the concept of boiling point elevation, which is a colligative property of solutions. Such properties depend on the number of solute particles in a solution, not their identity. Since toluene is the solvent, and a non-volatile solute is involved, its boiling point increases when the solute is added. The problem asks for the boiling point elevation constant, a value unique to toluene, and for the molar mass of the solute, which requires calculation.No graphs or diagrams are present to be explained further.

Answer: When a non-volatile is dissolved in a solvent it causes an elevation in the boiling point of…
