The volume required for a 5% solution is 5.7 L, while a 40% solution requires 4.3 L for the experiment.
<h3>What is defined as the percentage?</h3>
A percentage is a fraction of a whole represented as a number ranging from 0 and 100.
- In this question, you would like to make a 10 litre 20% solution by combining 5% and 40% concentrations.
- This question should have multiple answers.
- Supposing that total volume of the 5% and 40% solutions is 10 L (no solution wasted), you can calculate the volume of solution required.
The equation should be as follows:
If 'x' is the volume of a 40% solution, then the volume of a 5% solution is:
10 L = 40% solution volume + 5% solution volume
10 L = x + 5% volume of solution
10 L - x = 5% solution volume
The volume would then be calculated as follows:
(volume 20% × concentration 20%) = (volume 40% × concentration 40%) + (volume 5% × concentration 5%)
10 litre × 20% = x litre × 40% + (10- x) litre × 5%
10 L × 20% = x litre × 35% + 10 litre × 5%
x litre × 35 = 10 L × 20 - 10 L × 5
= 10 L × 15
x litre = 10 L × 15/35
x litre = 4.28 L
x litre = 4.3 L
40% solution volume = 4.3 L
The volume of 5% solution is equal to 10 L - 4.3 L = 5.7 L.
Thus, the volume of 5% solution requires is 5.7 L and volume of 40% solution required is 4.3 L.
