What is the resultant molarity of 20mL of a 3.5M solution is diluted to 100mL? Will mark brainliest
motikmotik

Answer:

The resultant molarity is 0,7 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 use the formula for dilutions:

C1 x V1 = C2 x V2

3,5 M x 20 ml= C2 x 100ml

C2= (3,5 M x 20 ml)/100ml

<em>C2= 0,7M</em>
