Interpretation : The higher vapor pressure is to be identified.
Concept Introduction : Colligative properties are those of solutions that depend only on the number of solute particles present, not on the nature of those particles. Depression in freezing point, elevation in boiling point, and vapor pressure lowering are important colligative properties.
Answer to Problem 7STP
The atomic window B will have a higher vapor pressure.
Explanation of Solution
The pressure that a vapor in a closed system applies to the liquid while they are in dynamic equilibrium is known as vapor pressure.
The vapor pressure of a solution containing a non-volatile solute is always lower than that of a pure solvent.
The atomic window A contains more solute particles along with water (solvent).
The atomic window B contains only water (solvent) without any solute particles.
The atomic window C contains fewer solute particles along with water (solvent).
Among the atomic windows, B will have higher vapor pressure since it is a pure solvent without solute.
In the case of window A, more solute particles are making it have a low vapor pressure. Window C will have higher vapor pressure than A but less than B.

- need help not sure what am doing wrong step by step please answer is 971A During the lecture, we calculated the Debye length at physiological salt concentrations and temperature, i.e. at an ionic strength of 150 mM (i.e. 0.150 mol/l) and a temperature of T=310 K. We predicted that electrostatic interactions are effectively screened beyond distances of 8.1 Å in solutions with a physiological salt concentration. What is the Debye length in a sample of distilled water with an ionic strength of 10.0 µM (i.e. 1.00 * 10-5 mol/l)? Assume room temperature, i.e. T= 298 K, and provide your answer as a numerical expression with 3 significant figures in Å (1 Å = 10-10 m).arrow_forwardInfluence of salt concentrations on electrostatic interactions 2 Answer is 2.17A why not sure step by step please What is the Debye length in a concentrated salt solution with an ionic strength of 2.00 mol/l?
