Answer:
At a 500 mL volumetric ballon, it will be added a little of distilled water, then 1 mL of the pure detergent, and then it will be added water until the meniscus. The solution will be agitated by inverting the flask until it's homogeneous.
Explanation:
In its pure state, the detergent has a 100% concentration. Thus, knowing that the product of the concentration by volume must be constant, we can do:
C1V1 = C2V2
Where C is the concentration, V is the volume, 1 is the pure detergent, and 2 the solution. So, let's find the volume of pure detergent needed to prepare 500 mL of the solution:
100*V1 = 0.2*500
100V1 = 100
V1 = 1 mL
Thus, at a 500 mL volumetric ballon, it will be added a little of distilled water, then 1 mL of the pure detergent, and then it will be added water until the meniscus. The solution will be agitated by inverting the flask until it's homogeneous.
All organisms need oxygen to survive
Well, it introduced atoms in this world and their functions. When the theory of atoms were created many more theory's came and we slowly figure out what the atoms do and what their functions are. The theory of an atom really surprised people because most of the people never knew the possibility of having living things inside of them.
Hope this helps.
PH=-log[ H₃O⁺] therefore [H₃O⁺]=10^-pH
[H₃O⁺]=10^-11
<span>[H₃O⁺]</span>=1.0x10^-11
