Question
Chapter 7, Problem 7.78EP
Interpretation Introduction
Interpretation:
The reason for liquid in one container evaporates at a faster rate than liquid in other container when both are in same temperature on a table top has to be mentioned.
Concept Introduction:
Evaporation is a process in which the molecules escape from the liquid phase to the gas phase. According to Kinetic molecular theory an evaporation can be explained as, not all the molecules present in a liquid or solid or gas possess the same the same kinetic energy and at any instant, some of the molecules may have above average kinetic energies and other may have below average kinetic energies as a result of collision between molecules. The molecules overcome attractive forces with other molecules.

Students have asked these similar questions
A student needs 240 mL of a 1/20 dilution of an undiluted stock solution. What volume
(mL) of the stock solution will be required?
Note: Your answer should be in numerical format to the nearest whole number (with a
decimal).
If you transferred 15 mL of an undiluted sample into 35 mL of diluting fluid, what dilution have you created?
(Note: provide your answer in decimal format to three decimal places.)
For the questions below be sure to show your work as well as the answer to the question.
In this week's lab you made 100ml of 10x PBS by dissolving 8 g NaCl, 1.2g Na₂HPO4 and 0.2 g
KH₂PO4 in water. You then adjusted the pH to 7.0.
A) How many mg of KH₂PO4 did you weigh out?
B) How many liters of 10x PBS did you make?
C) What is the final concentration of NaCl in your solution? (The molecular weight of NaCl is
58.44 g/mol)
D) What is the final concentration of Na₂HPO4 in your solution? (The molecular weight of
Na₂HPO4 is 141.96 g/mol)
E) What is the final concentration of KH₂PO4 in your solution? (The molecular weight of KH₂PO4
is 136.1 g/mol)
F) What is the hydrogen ion concentration of your solution (pH=7.0)?
G) If the initial pH of your solution was 6.29 would you need to add an acid or a base to adjust
the pH of a solution to pH 7.0?
10x PBS is a concentrated stock solution that is used to make more dilute solutions of PBS.
Starting with your 10xPBS stock solution, how would you…
