Answer:
You should dilute to 414.1 mL
Explanation:
Let's apply the dilution formula to solve this:
M conc . Vol conc = M dil . Vol dil
Molarity for concentrated solution → 4.50 M
Volume for concentrated solution → 60 mL
Molarity for diluted solution → Unknown
Volume for diluted solution → Answer
Let's determine the molarity for diluted solution with data given.
We convert the mass of KI to moles
3.25 g . 1 mol/166 g = 0.0195 moles
Let's convert the volume from mL to L
30 mL . 1 L/1000mL = 0.030 L
Molarity (mol/L) = 0.0195 mol /0.030L = 0.652 M
We replace the data in the formula
4.50 M . 60 mL = 0.652 M . Volume for diluted solution
(4.50M . 60mL) / 0.652M = Volume for diluted solution
414.1 mL = Volume for diluted solution
