To what volume should 25mL of 15M nitric acid be diluted to prepare a 3.0M solution?

125 mL will be the volume to be diluted

Explanation:

Dilution formula to be applied in this case:

Concentrated M. Concentrated volume = Diluted volume. Diluted M

Let's replace dа ta:

Concentrated M = 15 M

Concentrated volume: 25 mL

Diluted volume = ?

Diluted M = 3M

Lets replace: 15 M. 25 mL = Diluted volume. 3M

Diluted volume = (15 M. 25 mL) / 3 M → 125 mL
