Question

An unsaturated aqueous solution of NH3 is at 90.°C in 100. grams of water. According to Reference Table G, how many grams of NH3 could this unsaturated solution contain?
(1) 5 g (3) 15 g
(2) 10. g (4) 20. g

Answer 1

The solubility of solute in a solvent is at a maximum when the solvent no longer dissolves additional solute added to the solution. According to references, the solubility of NH3 in water at 90 C is 10 g NH3 / 100 g of water. So, the answer to the question is
(2) 10
