It reduces water due to friction
I hope this helps!<span />
Answer:
If you want the first option you need 2.5M.
If you want the second, you will end up with 120ml so your starting solution is:
0.5x (120/20) = 3.0M
This assumes that there’s no loss of volume on mixing. To remove that uncertainty, start with the 20ml of acid and add water, mixing, till you get the right volume.

Answer:
a) Eo = -C/ro + D exp(-ro/p)
1) dEN/dr = C/r² - D exp(-r/p)
2) Eo + C/ro = -Dexp(-ro/p)
C/ro = -Dexp(-ro/p) - Eo
∴ C = -ro(Dexp(-ro/p) + Eo)
3) EN = -(-ro(Dexp(-ro/p) + Eo)/r + Dexp(-r/p)
EN = ro(Dexp(-ro/p) - roEo/r + Dexp(-r/p)
EN + roEo/r = ro(Dexp(-ro/p) + Dexp(-r/p)
roEo/r = D(exp(-ro/p) + exp(-r/p) - EN
∴ Eo= r{D(exp(-ro/p) + exp(-ro/p) - EN}/ro
