Answer: The final concentration is 0.16 M.
Explanation:
According to the dilution law:
![M_1V_1=M_2V_2](https://tex.z-dn.net/?f=M_1V_1%3DM_2V_2)
where,
= molarity of stock solution = 1.60 M
= volume of stock solution = 54.0 ml
= molarity of diluted solution = ?
= volume of diluted solution = 218 ml
Putting these values:
![1.60\times 54.0=M_2\times 218](https://tex.z-dn.net/?f=1.60%5Ctimes%2054.0%3DM_2%5Ctimes%20218)
![M_2=0.40M](https://tex.z-dn.net/?f=M_2%3D0.40M)
Now 109 ml of this diluted solution is further diluted by adding 161 mL of water.
Again applying dilution law:
![0.40\times 109=M_3\times (109+161)](https://tex.z-dn.net/?f=0.40%5Ctimes%20109%3DM_3%5Ctimes%20%28109%2B161%29)
![0.40\times 109=M_3\times 270](https://tex.z-dn.net/?f=0.40%5Ctimes%20109%3DM_3%5Ctimes%20270)
![M_3=0.16M](https://tex.z-dn.net/?f=M_3%3D0.16M)
Thus the final concentration is 0.16 M
Answer:
Claim 1
Explanation:
I chose this claim because I believe that when the plates under the earth move or shift, that's what causes an earthquake and when everything starts to shake. If it was the other way around there wouldn't be any reason for an earthquake to start.
hope that helped :)
If you mean LiOH+HBr->LiBr+H2O
the answer is 0.4347mol LiBr and that equals (10/23)/80 gram LiBr
Answer:
This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs. ... Carbon dioxide is the waste product of cellular respiration that you breathe out each time you breathe.

Answer:
Ne with eight dots
Explanation:
On the periodic table, Neon is in group 8A. The group can be used to determine the number of valence electrons.
The dots in the Lewis structure diagram represent the number of valence electrons.
