Question

How many grams of NH3 can be dissolved in 50 grams of water at 50oC?

Answer 1

15 grams of  NH3 can be dissolved

Further explanation

Given

50 grams of water at 50°C

Required

mass of NH3

Solution

Solubility is the maximum amount of a substance that can dissolve in some solvents. Factors that affect solubility  

• 1. Temperature:
• 2. Surface area:
• 3. Solvent type:
• 4. Stirring process:

We can use solubility chart (attached) to determine the solubility of NH3 at 50°C

From the graph, we can see that the solubility of NH3 in 100 g of water at 50 C is 30 g

So that the solubility in 50 grams of water is:

= 50/100 x 30

= 15 grams
