In a solution of salt water, the mass of 250 g of salt is 15%. how many grams of salt are in the solution?

It is known from the condition that in a solution of salt water weighing 250 grams, salt is 15%. In order to find how many grams of salt in the solution we will compose and solve the proportion.

Let’s take a 100% saline solution weighing 250 grams. And using the variable x grams, we denote the weight of the salt in it.

Now let’s move on to drawing up and solving the proportion.

250 grams – 100%;

x gram – 15%.

250 / x = 100/15;

We need to find the unknown means of the proportion.

x = (250 * 15) / 100 = 3750/100 = 37.5 grams of salt in 250 grams of solution.
