Answer:
The total volum should be 26.64 L, this means we have to add 26.415 L
Explanation:
Step 1: Data given
Volume = 225 mL = 0.225 L
Molarity = 4.5 M
We dilute to a final concentration of 0.038 M
Step 2: Calculate the volume
C1V1 = C2V2
⇒ with C1 = the initial concentration = 4.5 M
⇒ with V1 = the initial volume = 0.225 L
⇒ with C2 = the final concentration = 0.038 M
⇒ with V2 = the final volume = TO BE DETERMINED
4.5M * 0.225L = 0.038M * V2
V2 = 26.64 L
The total volum should be 26.64 L, this means we have to add 26.415 L
