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.

The goal is to be able to quickly glance from the road in front of you to the road behind you without having to move or turn your body. Locate the levers or buttons that adjust the side mirrors. ... Older models often require you to manually adjust them using a lever or by pressing on the mirror itself.
The answer to that question is 58.4 g/mol.
Answer:
1.59x10⁻¹⁰m
Explanation:
To solve this question we must know that the length of the cubic cell, X, is equal to:
X = √8 * R
<em>Where R is the atomic radius of germanium</em>
And that in 1 unit cell there are 4 atoms of germanium.
To solve this question we must find the mass in 1 unit cell, with this mass we can find the volume of the cube and the length. With the length we can know the atomic radius:
<em>Mass in 1 unit cell -Molar mass Ge = 72.64g/mol:</em>
4 atoms Ge * (1mol / 6.022x10²³ atoms) = 6.64x10⁻²⁴ moles Ge
6.64x10⁻²⁴ moles Ge * (72.64g / mol) = 4.825x10⁻²²g Ge
<em>Volume unit cell:</em>
4.825x10⁻²²g Ge * (1cm³ / 5.32g) = 9.07x10⁻²³cm³
<em>Length unit cell:</em>
∛9.07x10⁻²³cm³ = 4.49x10⁻⁸cm * (1m / 100cm) = 4.49x10⁻¹⁰m
<em>Atomic radius Ge:</em>
4.49x10⁻¹⁰m / √8 =
<h3>1.59x10⁻¹⁰m</h3>
