Which has aqueous solution has the highest boiling point?

0.010 m Al(NO3)3

0.050 m C6H12O6

0.020 m NH4Cl

0.050 m NaCl

0.0050 m CO2

The boiling point of an aqueous solution depends on the concentration and nature of the solute. In this case, we can compare the boiling points of the given solutions based on their relative concentrations. The boiling point of an aqueous solution generally increases with increasing concentration.

Based on the given concentrations, the solution with the highest concentration is 0.050 m NaCl. Therefore, the solution of 0.050 m NaCl is likely to have the highest boiling point among the given options.
