Final answer:

To find the new boiling point, calculate the molality of each solute, apply the van 't Hoff factor and the boiling point elevation constant, and add the resulted elevation to water's normal boiling point of 100.00°C.

Step-by-step explanation:

To calculate the new boiling point of a solution given the grams of water, the grams of Fe(NO3)3, and the grams of C6H12O6, you will need to apply the concept of boiling point elevation in colligative properties.

First, find the molarity of each solute in the solution. Then use the molal boiling point elevation constant (Kb) for water and the van 't Hoff factor (i) for each solute to calculate the boiling point elevation, ΔTb. The van 't Hoff factor is the number of particles into which a compound dissociates in solution. For Fe(NO3)3, i is 4 (1 Fe3+ + 3 NO3-), and for C6H12O6 (glucose), i is 1 since it does not dissociate.

Next, calculate the boiling point elevation of each solution separately using the formula ΔTb = i * Kb * m, where m is the molality of the solution. Then, add these values to the normal boiling point of water, 100.00°C, to get the new boiling point for each solution.

Remember to verify your calculations as a form of self-assessment to ensure the results are reasonable.
