I think I still have 2g in both solutions, but I know if I look at molartiy this changes.
You know the grams, and you know the old an new volumes. How does it change?
First think: you start with some amount, you add more solvent, your final answer has to be less than it was before?
Also think, by how much less: If you had a gram, in 10 mL, and you added 90 ml more ... you'd have the same gram, but now in 100. The 100 is different from 10 by how?
Please try to put all your work, from start to finish, in one posting. Otherwise the thread will grow to multiple pages, and we'll forget what we've already done.
