Answer:
The new molarity is 0,96 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
2,4 M x 100ml = C2 x 250 ml
C2= (2,4 M x 100ml)/250 ml
<em>C2= 0,96 M</em>
