Suppose that the mixture in problem 4 is at 15 OC, where the pure vapor pressures are 12.5 mmHg for water and 32.1 mmHg for ethanol. According to Raoult’s Law, the pressure of a component in a solution is equal to its pure vapor pressure times its mole fraction, that is PA = ( ) (XA). Use Raoult’s law to determine the vapor pressure of each component in the solution. Then, add them to find the total vapor pressure. Use significant figures. Show all equations and conversion factors.

Which element in the third period would you expect to have the larger atomic radius, sodium (na) or sulfur (s)? a. sodium, because it has a higher effective nuclear charge attracting electrons in fewer energy levels. b. sodium, because it has fewer protons attracting electrons in the same energy levels. c. sulfur, because it has more protons attracting electrons in more energy levels. d. sulfur, because it has a higher effective nuclear charge attracting electrons in the same energy levels.
