TheIn a laboratory activity, each of four different masses of KNO3(s) is placed in a separate test tube that contains 10.0grams of H₂O at 25°C.When each sample is first placed in the water, the temperature of the mixture decreases. The mixture in each test tube isthen stirred while it is heated in a hot water bath until all of the KNO3(s) is dissolved. The contents of each test tube arethen cooled to the temperature at which KNO3 crystals first reappear. The procedure is repeated until the recrystallizationtemperatures for each mixture are consistent, as shown in the table below.Data Table for the Laboratory ActivityMass of Mass ofTemperature ofRecrystallizationMixtureKNO3H₂O(g)(9)(°C)14.010.0245.010.032twollwana ban7.510.045410.010.058Refer to Figure 1 and answer the following Question:Compare the freezing point of mixture 4 at 1.0 atm to the freezing point of water at 1.0 atm.AnswerPURE23(DE) 10.1
