A liter of one solution contains 20 g of salt, a liter of another solution is the second more. How many grams of salt is in the new solution?
Before finding the weight of the salt in the new solution, let us determine its weight in the second solution.
Since we know that it contains 3 times more salt than the first, we get:
20 * 3 = 60 grams.
Find the total weight of the salt.
To do this, add the weight of the salt of the second solution to the weight of the salt of the first solution.
Will be:
20 + 60 = 80 grams.
The total weight of the solution will be:
1 + 1 = 2 liters.
2 l = 2000 grams.
The concentration of salt in the solution will be equal to:
80/2000 * 100% = 0.04 * 100% = 4%.
Answer: The solution contains 80 g of salt.
