To what volume should you dilute 50.0 mL of a 4.50 M KI solution so that 28.5 mL of the diluted solution contains 2.75 g of KI?

Answer 1

Convert 2.75 g to moles KI.
??moles = grams/molar mass.
Then M KI is ?? moles/0.0285 L = ?M

You want to dilute the 4.50 M KI solution starting with 50 mL and you want the final solution to be ?M
4.50M x (50mL/x mL) = ?M
Solve for x in mL.
Check my thinking. Check the work.
