We’re being asked to calculate for the molality of a solution prepared by dissolving 10.66 g of potassium chlorate in 74.9 g of water.

When calculating for molality, we use the following equation:

molality(m)=moles solutekg solvent

solution → water is the solvent (H2O)
                     solute → potassium chlorate 

                          Potassium → Group 1A → +1 charge → K+
                          Chlorate → polyatomic ion → ClO3-

                          Potassium Chlorate:

We will calculate the molality of the solution using the following steps:
