From the information below, determine the mass of NH3 in 500 grams of concentrated ammonia?
Ammonia, concentrated: 28% solute by mass; Density 0.90g/mL
The ammonia solution is 28% by mass of solute; this means that 100 mL of the solution contains 28 g ammonia.
Again, the density of the ammonia solution is 0.90 g/mL.
Therefore, the mass of the ammonia solution can be easily found out using the density and the volume.
Sorry about that. What wasn’t helpful?
