Answer:
The resultant molarity is 0,7M.
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 use the formula for dilutions:
C1 x V1 = C2 x V2
3,5M x 20 ml = C2 x 100ml
C2=(3,5 M x 20 ml)/ 100ml
C2=0,7M
