Solubility of ammonium nitrate in water at 15°C is 173 g.
Solubility of ammonium nitrate in water at 75°C is 499 g.
m(water) = 127 g.
15°C:
173 g : 100 g = m(NH₄NO₃) : 127 g.
m(NH₄NO₃) = 219,71 g.
75°C:
499 g : 100 g = m(NH₄NO₃) : 127 g.
m(NH₄NO₃) = 633,73 g.
m(NH₄NO₃) = 633,73 g - 219,71.
m(NH₄NO₃) = 414,02 g.
