A , i think because pure water won't dissolve the powder fast.
It is not, because the mass is being conserved and not changed.

Ideal gas law:
pv = nrt
nr is mole times the ideal gas constant, these are both held constant (do not change value)
pv/t = nr
Then you can set the conditions before = after
pv/t = PV/T
before: (convert to Kelvin)
(0.995)(5.27x10^4) / 305
After: (convert to Kelvin)
(0.720)V / 206.3
solve for V , volume after.
(0.995)(5.27x10^4) / 305 = (0.720)V / 206.3
4.926 x 10^4 L = V
Make an observation.
Ask a question.
Form a hypothesis, or testable explanation.
Make a prediction based on the hypothesis.
Test the prediction.
Iterate: use the results to make new hypotheses or predictions. Hope this helps
