| **The salt water solution contains 79.58 g of salt, which is 0.2 mass of the solution. How many grams of water is in the solution?**

To solve this problem, we introduce a conditional variable “X”, through which we denote the amount of water in the solution. Then, taking into account that we will consider the entire solution as a unit, we will find what part is occupied by water in the solution. To do this, subtract 0.2 from 1. As a result, we get 1 – 0.2 = 0.8. Now let’s make the following proportion: 79.58 grams of salt is related to 0.2 as X is to 0.8. As a result, we get the equation: 0.2X = 79.58 x 0.8. Solving this equation, we get X equal to 318.32 grams. If rounded up, we get 318 grams of water in solution.

Answer: 318 grams of water.
