Temperature (°C)
1000 g of ammonium nitrate was dissolved in 200 mL of water at a temperature of 80°C.
The solution was then cooled.
,
At what temperature did the solution first become saturated?
(1mr
The solution is cooled further to 30°C and held at that temperature long enough to
allow for the formation of crystals of ammonium nitrate.
How many grams of the original 1000 g ammonium nitrate will be crystallis
at 30°C? (Show your working clearly.)
what is the answer to that problem
