56 L of ammonia was dissolved in 0.2 water. what is the mass fraction of the substance in the resulting solution.

1. Determine the total volume of the solution: 0.2 + 56 = 56.2 liters.

2. The mass fraction of a substance can be determined in%. It shows how much ammonia takes up in an aqueous solution.

Let’s write the proportion:

56.2 L – 100%

56 l – x%.

x = 56 * 100 / 56.2;

x = 5600 / 56.2;

x = 99.64.

Answer: the mass fraction of ammonia in the solution is 99.64%.
