Answer:
91.7 mL are needed to prepare the diluted solution
Explanation:
When you dilute a determined solution the molarity and the volume for both solutions (diluted and concentrated), are the same.
M concentrated . Concentrated volume = M diluted . Diluted volume
3 M . Concentrated volume = 1.10 M . 250 mL
Concentrated volume → ( 1.10 M . 250 mL) / 3M = 91.7 mL
