20%
The codeine percentage strength of the solution is 20%
- The term "percent strength" describes the proportion of a material that has dissolved in a given volume of liquid.
- Knowing how parts relate to wholes is the secret of % strength: A percent is equal to x parts out of 100 overall.
<h3>Meaning of percentage strength</h3>
- The amount of a liquid is often measured, and the % strength tells you how many parts by volume of the active ingredient are present.
- 100 parts by volume are included in the total volume of the solution or liquid preparation.
<h3>How do you determine a solution's strength?</h3>
Mass of solute times strength of solution(g) Amount of the solution(L)
- The amount of solute dissolved in grams per liter of the solution is used to determine the solution's strength.
- It stands for the solution's potency or concentration.
- It uses grams per liter to express.

Answer:
This question is incomplete
Explanation:
This question is incomplete, however, there are some basic things that be used to answer the completed question on your own. Flame test is a test that is used to identify metal ions in a compound. Although, not all metal ions produce a colour in a flame test.
In a flame test, a "clean wire loop" is dipped in an unknown solid/mixture of solids, the loop where the solids must have attached to is then placed in the tip of a blue flame (perhaps of a bunsen burner). A colour change/changes is then observed during the course of this process. Some popular metal ions and there colour in flame test are listed below
Lithium ion ⇒ red
Sodium ion ⇒ yellow
Potassium ion ⇒ lilac
Calcium ion ⇒ orange-red
Barium ion ⇒ pale-green
Copper ion ⇒ blue-green
rubidium ion ⇒ red-violet
Lead ion ⇒ gray white
The number of different colours observed will ultimately determine the number of elements exposed to the flame

Freak you poop but moms swig
When burning sodium (Na) in oxygen (O2), you get sodium oxide (Na2O) and/or sodium peroxide (Na2O2). At high pressures, you can additionally get sodium superoxide (NaO2).
4 Na + O2 → 2 Na2O, and then partially 2 Na2O + O2 → 2 Na2O2.
Under normal conditions, approximately 20% of the mixture is Na2O2.
6 Na + 2 O2 → 2 Na2O + Na2O2
