An iodine solution is essentially a mixture of water and the element iodine. An iodine solution is described using a percentage which indicates what percent of the entire solution is iodine only.
You have one beaker which contains an unknown amount of a 15% iodine solution and another beaker which contains an unknown amount of a 20% iodine solution. You also have a third beaker which contains 100 mL of a 10% solution.
You add only half of the 20% solution to the 15% solution, and the mixture becomes an 18% solution. Then you add 50 mL of the 10% solution to the whole mixture. After this, the whole entire mixture of the 15% solution, half of the 20% solution, and 50mL of a 10% solution becomes a 14% solution.
How much liquid (in mL) was originally in the beaker with the 20% solution and how much liquid (in mL) was originally in the beaker with the 15% solution?
