Final answer:
To calculate the new boiling point of the solution, use the equation ∆Tb = Kb · m · i, where ∆Tb is the change in boiling point, Kb is the molal boiling point elevation constant, m is the molality of the solute, and i is the vant Hoff factor.
Step-by-step explanation:
To calculate the new boiling point of the solution, we can use the equation ∆Tb = Kb · m · i, where ∆Tb is the change in boiling point, Kb is the molal boiling point elevation constant, m is the molality of the solute, and i is the vant Hoff factor. The molality can be calculated by dividing the moles of solute by the mass of the solvent in kg.
In this case, we have 126 g of water, 5.0 g of Fe(NO₃)³, and 5.0 g of glucose C₆ H ₁₂O₆. The molality of Fe(NO₃)³ can be calculated by converting grams to moles and dividing by the mass of water in kg. The molality of glucose can be calculated in the same way. Finally, plug the values into the equation to find the change in boiling point.
