To calculate the frequency from the given data, this simple formula should do it: f=\frac{n}{t} where : n = the number of (complete) waves that propagated [wave(s)] t = the time period [second(s)] The number of waves itself isn't clear since the meaning of the word 'loop' is vague. Anyway...

Thanks a bunch!

So the answer is definitely 2,1,1?

As water evaporates, the amount of solvent (water) in both solutions decreases. For solution (2) the mole fraction of water should decrease in value. If I'm not mistaken, for solution (1) (which is saturated), as the water evaporates, some of the salt solidifies as well in proportion. So, the...

I've made a mistake for question a) & c) For question a), solution (2) has a greater PH2O value because the amount of solute (in this case NaCl) is less than that of solution (1) therefore Xsolvent of solution (2) is greater than that of solution (1). For question c), solution (1) has a...

Homework Statement : As the picture shows, there are two NaClaq solutions. One is saturated while the other is not and both of them are at the same temperature. There are three questions asked: a) Above which solution is the vapor pressure of water, PH2O, greater? Explain. b) Above one of these...
