In a salt water solution, there are 184 g of salt, which is 0.4 mass of the solution.

In a salt water solution, there are 184 g of salt, which is 0.4 mass of the solution. How many grams of water is in the solution?

It is known from the condition that there are 184 grams of salt in the salt water solution, which is 0.4 mass of the solution. In order to find how many grams of water in the solution we will compose and solve the proportion.

Let’s take 1 weight of the entire solution. Let’s calculate the weight of water in solution:

1 – 0.4 = 0.6.

Let us denote by the variable x the weight of water in solution.

Let’s compose and solve the proportion:

184 grams – 0.4;

x gram – 0.6.

184 / x = 0.4 / 0.6;

We are looking for a variable as an unknown average term of the proportion:

x = (184 * 0.6) /0.4 = 110.4 / 0.4 = 276 grams of water in solution.
