Answer:
314mL OR 0.314L
Step-by-step explanation:
this requires the dilution formula M1V1 = M2V2 where
M1 = initial concentration
V1 = initial volume
M2 = final concentration
V2 = final volume
In this case, we are solving for V1 where M1 = 5.65M, V1 = 250.0 mL, and M2 = 4.50M
Plugged into the equation we get:
(5.65M)(250.0mL) = (4.50M)V2
divide both sides by 4.50M and it becomes (M cancel)
V2 = 314mL
