I think I've arrived at the conclusion that its just a poor problem. The homework site I am using will generate a similar problem for practice, with slight changes to initial variables. Heres another- solving the second part without the glass results in a logically consistent solution...

Your right, my answer makes no sense with regard to initial amount of steam. I think Id had my head buried in the numbers for too long at that point.

I think I figured it out. Or figured out a way to arrive at an answer within 1/10th of a gram lol. Whereas the first part of the problem required you to include the heat necessary to raise the temperature of the glass, I could only arrive at the "correct answer" for the second part by not...

OK, I think I get it. The water hits 100C and starts to undergo phase change. As soon as the initial steam hits 100C the system is in equilibrium. I'll see if i can work that out. Thanks for your help!

Thanks for the reply. I am not sure I understant how latent heat works in this scenario. In a system like this, with water and steam, if one undergoes a phase change, does the latent heat affect the temperature of the other? For example, the water stays at 100C until it has completely changed to...

The second question is where I'm lost. The answer to the first question is 5.39 grams. The second is 10.3 grams. Until I saw the answer I was setting the equation up as if some of the original steam had condensed. But it appears that some of the original water changed into steam. Is it necessary...
