The unknown concentration of the new solution is determined by the conditional variable “Y”.
Using the information from such an example, we get the following expression: Y = ((30 x 150/100) / (150 + 350)) x 100.
When we make the calculation, we will have the following value Y = ((3 x 15) / 500) x 100 = (45/500) x 100 = 45/5 = 9%.
Answer: 9% is the concentration of the new solution.
