a qualitative observation is when somehthings appearance changes like form red to blue, and qualitative is when the umber of something changes.

To find the number of miles of NaOH, simply convert 49.80 ml into L, and then multiply it to the molar concentration of NaOH, so in this case the number of moles would be 0.04980 moles of NaOH. This would also equal the moles of H2O, as there is a 1:1 ratio between moles of base and moles of H2O.
I think that it is D because the higher the molecular mass, the higher it's boiling point. I hope that helped:) Bye!
A specific mass of a gas has a fixed volume at room temperature
