In what proportion should you combine a 2:5 soaking solution and distilled water to create a 300 ml of a 1:20 solution
To find the proportion of the 2:5 soaking solution and distilled water needed to create a 300 ml of a 1:20 solution, we need to break down the problem into two parts:
1. Calculate the volume of the soaking solution needed.
2. Calculate the volume of distilled water needed.
Let's start with the first part:
1. Calculate the volume of soaking solution needed:
A 1:20 solution means that for every unit of the soaking solution, there should be 20 units of the total solution. In this case, since the total desired solution volume is 300 ml, the proportion would be given as x:300, where x represents the volume of the soaking solution.
To determine the proportion, we can set up the following equation:
x / 300 = 1 / 20
To solve for x, we cross-multiply and solve for x:
x = (1 / 20) * 300
x = 15
Therefore, 15 ml of the soaking solution is needed.
Now, let's move on to the second part:
2. Calculate the volume of distilled water needed:
Since we know that the total desired solution volume is 300 ml and we already have 15 ml of the soaking solution, we can calculate the volume of distilled water needed as follows:
Volume of distilled water = Total desired volume - Volume of soaking solution
Volume of distilled water = 300 ml - 15 ml
Volume of distilled water = 285 ml
Therefore, 285 ml of distilled water is needed.
To summarize, in order to create a 300 ml of a 1:20 solution, you would need to combine 15 ml of the soaking solution and 285 ml of distilled water.
