Answer 1

1. A solution contains 40g of Nall per 100g of water at 100°c. The solution is saturated. 2. A solution contains 50g of ka per 100g of water at 25°C. The solution is super saturated. 3. 4. A solution contains 10g of KNO3 per 100g of water at 30°c. The solution is unsaturated. The molarity of the solution is 1000x 27. 342.29658236.6 = 0.333(M) 5. The mass of Nace in a 55ml sample of a 3.5M salire solution is 3.5x58.44 XSS ( where molecular 1000 weight of Nach = 11:2497g is 58.44 g/mol) Molecular weight of ka = 74.5513 2.6 g Kd = 2.6 2 = 0.0348 of note (1) To make it ufm) are have to add rooox 0.0348 6. e qosul
