Wow, now this one is a hard one, took me quite a while to figure it out but here it is:
$120.904(x)+122.904(1-x)=121.76 \\ 
120.904x-122.904x+122.904=121.76 \\ 
-2x+122.904=121.76 \\ 
-2x=-1.144 \\ 
x=.572 \\ 
1-.572=.428$
The abundances of the two isotopes is:
Antimony-121 = 57.2%
Antimony-123 = 42.8%

What is true if a liquid and a gas are in equilibruim

o-na [289]

Answer:

We can see that at the boiling point, both liquid and gas are in equilibrium with one another. This is true for any applied pressure and boiling point temperature combination. As a result, we see liquid-gas equilibrium for every temperature and pressure combination on the graph in Figure 13.6.
