<span>You know how when you dilute something, you would divide by the volume, and when you take an aliquot, you would multiply by the volume? Well, since you're working backwards, you do the opposite operations.
3.17E-6 M (150.0 mL / 10.00 mL) = 4.76E-5 M (150.0 mL / 10.00 mL) = 7.13E-4 M (150.0 mL / 10.00 mL) = 1.07E-2 M (150.0 mL / 10.00 mL) = 0.160 M
So the original stock was a 0.160 M HBr solution.</span>
Solution :
According to the Graham's law of diffusion, we know that, the rate of the diffusion varies inversely to the molar mass of the gas, i.e.
Rate of diffusion, 
where, the 'M' is the molar mass of the gas.
Now in the case of the isotopes of the Krypton,
Atomic mass of 
= 80 AMU
Atomic mass of 
= 82 AMU
Atomic mass of 
= 83 AMU
So the ratio of the rate of diffusion of the three isotopes are :
Dividing the above three with the smallest number among the three i.e. 0.10976, we get the relative rates of diffusion.
∴
= 1.02 : 1.01 : 1
Hence the relative rate of diffusion are :
If im not mistaken about like three orr four
yea its four cuz its hard to exaplin lol
Child psychology is the study of subconscious and conscious childhood development. Child psychologists observe how a child interacts with their parents, themselves, and the world, to understand their mental development.
The answers include the following:
- Graphite conducts electricity because it has delocalised electrons which makes it possible for the electrons to move freely.
- Graphite is slippery because it has layers which makes it possible for the atoms to slide over each other.
<h3>What is Graphite?</h3>
This is referred to as an allotrope of carbon and it is the most stable form. it is used in the production of substances such as pencil, electrode etc.
Graphite is able to conduct electricity because of the presence of delocalized electrons and is slippery due to its atoms being able to slide over one another.
