Answer:
Ok; first of all, you must correct the Molecular Formula; FeSO4•7H20
So, work out the Molar Mass;,
(4x18)O+ 55.? Iron + 32 Sulphur, PLUS
(7x 18) H2O = 1 molar mass.
Now, take that times 5.24, show your work & check the Mol. Weights, I am going by memory.

Answer:
- About 18 g of NH₄Cl will precipitate.
Explanation:
The <em>table G</em> is the graph of the solubility curves for several solutes which is attached.
The second picture identifies the solubilities for the NH₄Cl at 50ºC and 10ºC.
The solubility of NH₄Cl at 50ºC is about 52 g/ 100 g of water.
The solubility of NH₄Cl at 10ºC is about 34 g / 100 g of water.
Then, at 50ºC 100 g of water saturated with NH₄Cl contains about 52 g of NH₄Cl and 100 g of water saturated with NH₄Cl contains 34 g of NH₄Cl.
The difference, 52g - 34 g of NH₄Cl shall precipitate:
52 g - 34 g = 18g ← answer
