Answer:
0.25L
Explanation:
Using the dilution formula
C1V1=C2V2
C1=6M
V1?
C2=0.75M
V2=2.0L
V1= C2V2/C1
V1=0.75*2.0/6
V1=0.25L
Answer:
We need 0.25 L of the 6.0 M solution
Explanation:
Step 1: Data given
Molarity of the Fe(SCN)2 solution = 6.0 M
Volume of the 0.75 M solution = 2.0 L
Step 2: Calculate volume
C1*V1 = C2*V2
⇒ with C1 = the initial concentration = 6.0 M
⇒ with V1 = the initial volume = TO BE DETERMINED
⇒ with C2 = the new concentration = 0.75 M
⇒ with V2 = the new volume = 2.0 L
6.0M * V1 = 0.75M * 2.0L
V1 = (0.75 M * 2.0L) / 6.0 M
V1 = 0.25 L
We need 0.25 L of the 6.0 M solution
