When 5 grams of salt dissolve in 30 grams of water, what is the resulting mass of the mixture?

The resulting mass would be 35 grams.

Explanation: Mass cannot be destroyed, there would be no need to re-measure the mass. Therefore, if we add the masses we get 35.

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.
