One of the solutions to be studied contains 100 grams of water and 5 grams of "Y" and the melting point measurements indicate that the solution is 0.54 molal. From this prepared solution, a 50 gram sample is taken at 0 ° C and solidified in a freezer that is at a temperature of -18 ° C. Data: ΔH fus of the studied solution = 0.33 KJ / gr. The molecular weight of Y = 150 -Calculate the entropy change (J / ° K) of the solution when the 50 gram sample is frozen.
It is desired to prepare a new drug "Y" for which various degrees of dissolution of the product in water are prepared to measure the efficacy of the drug in various doses and it is also desired to determine the relationship between the entropy changes of the Samples under various situations.
