Question
All three Please!!!!!!!!!!!!!!!!!!!!!!
In the freezing point experiment, the time vs. temperature curve for the pure solvent cyclohexane flattens out (i.e., stays constant with time) when the freezing point is reached. However, with the solution of unknown in cyclohexane, the temperature continues to drop with time. what is the reason for this difference? EXPLAIN The reason for this difference is because the ununowm in the eyclohexane causes the temperature to keep dropping. Why? JDY SHEET (13-16) PROBLEMS What is the molarity of a 0.133 N H2C2O4 solution? 3.99M 2+24+64=90/2 0.133 times 30= 3.99 The density of 4.65 M H2SO4 is 1.36 g/mL. What is the molality of this solution?Explanation / Answer
A)
The freezing point of pure water is 0
