Answer:
1.55
Explanation:
-log(M)=pH

Not sure if this is what you mean but l= A/w
(length equals area divided by width)
Answer:
A pH=3 is 1000 times as acidic as a pH=6.
Answer:
The final concentration is 0,151 M.
Explanation:
A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).
We convert the unit of volume in L into ml: 3,25 x 1000= 3250 ml
We use the formula for dilutions:
C1 x V1 = C2 x V2
C2= (C1 xV1)/V2
C2= (32, 5 ml x 15, 1 M)/ 3250 ml
<em>C2=0,151 M</em>
