Answer:
The new molarity is 0,22M
Step-by-step 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
0,89 M x 0,723L= C2 x 2.880 L
C2= (0,89 M x 0,723L)/2.880 L
C2= 0,22M
