Answer:
136.36 mL
Explanation:
Here we have to use the dilution formula
From C1V1= C2V2
Where;
C1= initial concentration of the solution= 12.0 M
C2= final concentration of the solution= 2.20 M
V1 = initial volume of the solution= 25.0 ml
V2= final volume of the solution= ?????
Then recall;
C1V1=C2V2
V2 = C1V1/C2
Substituting values from the parameters given;
V2= 12.0 × 25.0 / 2.20
V2= 136.36 mL
It is 95% ethanol and 5%water
I’m pretty sure hope you get it right!

Answer:
6 mols HCl
Explanation:
(I'm an AP chemistry student but not perfect at this stuff)
you can use the Molarity=Moles/L equation here:
(6M)=(moles HCl)/(1L)
divide by 1 on both sides to isolate the moles of HCl
this gets you 6 moles HCl.
Again I'm just a student so my answer might be wrong, but this question should just require the M=mols/L equation :).
