All solutions are composed of one of the compounds completely dissolved in water. Solubility refers to the ability of a substance to dissolve completely in water at a given temperature and is expressed as a percent of compound per unit mass of solution. The mass of a solution is the sum of the mass of the water and the mass of the compound dissolved in the water.
A new solution is made by pouring 100 grams of water into a 160 gram solution that is 5% Compound X. At 50° C, what is the maximum number of grams of Compound X that can be added into the new solution so that all of the added Compound Xdissolves?
A. 26
B. 20
C. 18
D. 10
E. 8

Content of X is 5% of 160gm = 8gm compound X
Total volume of the solution = 160 + 100 = 260
Let's say p gm of compound X is added in the solution.
From the graph, we can conclude that the solubility is approx 12%
Hence, \(\frac{p+8}{p+260}\) = \(\frac{12}{100}\)
By solving, we will get p = 26.36
